Check Digit Verification of cas no

The CAS Registry Mumber 13493-24-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,9 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13493-24:
(7*1)+(6*3)+(5*4)+(4*9)+(3*3)+(2*2)+(1*4)=98
98 % 10 = 8
So 13493-24-8 is a valid CAS Registry Number.

Cross coupling of acyl and aminyl radicals: Direct synthesis of amides catalyzed by Bu4NI with TBHP as an oxidant

Liu, Zhaojun,Zhang, Jie,Chen, Shulin,Shi, Erbo,Xu, Yuan,Wan, Xiaobing

experimental part, p. 3231 - 3235 (2012/05/05)

A radical solution: A Bu4NI/tert-butyl hydroperoxide (TBHP) catalyzed synthesis of amides through a cross-coupling reaction between acyl and aminyl radicals is described. This method involves the combination of aldehyde C-H bond functionalization and decarbonylation of N,N-disubstituted formamides (see scheme). The cross-coupling is metal-free, has a wide substrate scope, operational simplicity, and gives high yields on scale-up. Copyright
