Check Digit Verification of cas no

The CAS Registry Mumber 345252-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,2,5 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 345252-61:
(8*3)+(7*4)+(6*5)+(5*2)+(4*5)+(3*2)+(2*6)+(1*1)=131
131 % 10 = 1
So 345252-61-1 is a valid CAS Registry Number.

A general method for the one-pot reductive functionalization of secondary amides

Huang, Pei-Qiang,Huang, Ying-Hong,Xiao, Kai-Jiong,Wang, Yu,Xia, Xiao-Er

, p. 2861 - 2868 (2015/03/18)

A one-pot reaction for the transformation of common secondary amides into amines with C-C bond formation is described. This method consists of in situ amide activation with Tf2O-partial reduction-addition of C-nucleophiles. The method is general in scope, which allows employing both hard nucleophiles (RMgX, RLi) and soft nucleophiles, as well as enolates. With the use of soft nucleophiles, the reaction proceeded with high chemoselectivity at a secondary amide in the presence of ester, cyano, nitro, and tertiary amide groups.
