Check Digit Verification of cas no

The CAS Registry Mumber 1042737-42-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,7,3 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1042737-42:
(9*1)+(8*0)+(7*4)+(6*2)+(5*7)+(4*3)+(3*7)+(2*4)+(1*2)=127
127 % 10 = 7
So 1042737-42-7 is a valid CAS Registry Number.

Pd-Catalyzed Intramolecular Cyclization via Direct C-H Addition to Nitriles: Skeletal Diverse Synthesis of Fused Polycyclic Indoles

Wang, Ting-Ting,Zhao, Lang,Zhang, Yan-Jing,Liao, Wei-Wei

, p. 5002 - 5005 (2016)

The first example of Pd-catalyzed intramolecular C-H addition of indoles bearing cyanohydrin components at the C(3), C(2), and N(1) positions to nitriles is described. A wide range of functionalized partially saturated carbazoles, tetrahydropyrido[1,2-a]indole, and carbazoles can be prepared in good to excellent yields under the optimal conditions. In addition, fused polycyclic indoles with seven- or eight-membered rings can also be formed smoothly.

Cu-catalyzed β-functionalization of saturated ketones with indoles: A one-step synthesis of C3-substituted indoles

Yang, Zhao,Liu, Chengkou,Zeng, Yu,Zhang, Jingming,Wang, Zhixiang,Fang, Zheng,Guo, Kai

, p. 89181 - 89184 (2016/10/03)

An effective one-pot synthesis of β-indolylketones from saturated ketones and indoles was developed. It is noteworthy that this methodology has a good functional group tolerance (alkyl, nitro, halogen, hydroxyl, methoxyl, carboxyl and ester) and is of great significance to the preparation of many indole heterocycles.
