890522-63-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 890522-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,5,2 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 890522-63:
(8*8)+(7*9)+(6*0)+(5*5)+(4*2)+(3*2)+(2*6)+(1*3)=181
181 % 10 = 1
So 890522-63-1 is a valid CAS Registry Number.

Palladium-catalyzed allylation of sulfonyl hydrazides with alkynes to synthesize allylic arylsulfones

Lu, Chuan-Jun,Chen, Hong,Chen, Dong-Kai,Wang, Hong,Yang, Zhen-Ping,Gao, Jianrong,Jin, Hongwei

, p. 10833 - 10839 (2016)

A novel method for the construction of allyl arylsulfone derivatives was developed by palladium catalyzed allylation of sulfonyl hydrazides with alkynes. A series of structurally diverse allyl arylsulfones can be regioselectively synthesized in high yields under mild conditions.

NaHSO3-Mediated Direct Synthesis of Sulfinic Esters from Sulfonyl Hydrazides under Transition-Metal-Free Conditions

Zhang, Guofu,Fan, Qiankun,Wang, Huimin,Zhao, Yiyong,Ding, Chengrong

supporting information, p. 833 - 837 (2020/12/07)

We have developed a protocol for the NaHSO3-promoted esterification of sulfonyl hydrazides with alcohols for the synthesis of sulfinic esters. Various sulfonyl hydrazides could be converted to the corresponding sulfinic esters in good to high yields. The merits of this protocol include mild transition-metal-free reaction conditions, an inexpensive and available reagent, and operational simplicity. Controlled experiments reveal that this transformation probably undergoes via a radical pathway. (Figure presented.).
