Check Digit Verification of cas no

The CAS Registry Mumber 1353562-24-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,5,6 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1353562-24:
(9*1)+(8*3)+(7*5)+(6*3)+(5*5)+(4*6)+(3*2)+(2*2)+(1*4)=149
149 % 10 = 9
So 1353562-24-9 is a valid CAS Registry Number.

Catalyst-Free Transamidation of Aromatic Amines with Formamide Derivatives and Tertiary Amides with Aliphatic Amines

Yin, Jiawen,Zhang, Jingyu,Cai, Changqun,Deng, Guo-Jun,Gong, Hang

supporting information, p. 387 - 392 (2019/01/11)

A simple catalyst- and promoter-free protocol has been developed for the transamidation of weakly nucleophilic aromatic amines with formamide derivatives and low-reactivity tertiary amides with aliphatic amines. This strategy is advantageous because no catalyst or promoters are needed, no additives are required, separation and purification is easy, and the reaction is scalable. Significantly, this strategy was further applied to synthesize several pharmaceutical molecules on a gram scale, and excellent yields were achieved.

KOtBu-Promoted Transition-Metal-Free Transamidation of Primary and Tertiary Amides with Amines

Ghosh, Tridev,Jana, Snehasish,Dash, Jyotirmayee

supporting information, p. 6690 - 6694 (2019/09/12)

This work discloses transamidation of primary and tertiary amides with a range of aryl, heteroaryl, and aliphatic amines using potassium tert-butoxide. The reaction proceeds at room temperature under transition-metal-free conditions providing secondary amides in high yields. Moreover, reaction of cyclopropyl amine with tertiary amides proceeds with ring-opening to provide a rapid access to enamides.

Aerobic radical-cascade cycloaddition of isocyanides, selenium and imidamides: Facile access to 1,2,4-selenadiazoles under metal-free conditions

Fang, Yi,Zhu, Zheng-Lin,Xu, Pei,Wang, Shun-Yi,Ji, Shun-Jun

supporting information, p. 1613 - 1618 (2017/06/05)

A novel and facile metal-free method for the green synthesis of 1,2,4-selenadiazol-5-amine derivatives through the aerobic radical-cascade multi-component reactions of isocyanides, selenium powder and imidamides is reported herein. O2 in the air was employed as the green oxidant to achieve the cycloaddition with the generation of H2O as the sole by-product. It also features good functional group compatibility and broad substrate scope. In addition, this method was successfully applied to the functionalization of biologically active molecules.
