Check Digit Verification of cas no

The CAS Registry Mumber 514808-21-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,4,8,0 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 514808-21:
(8*5)+(7*1)+(6*4)+(5*8)+(4*0)+(3*8)+(2*2)+(1*1)=140
140 % 10 = 0
So 514808-21-0 is a valid CAS Registry Number.

Direct amidation of carboxylic acids with tertiary amines: Amide formation over copper catalysts through C-N bond cleavage

Xiong, Biquan,Zhu, Longzhi,Feng, Xiaofeng,Lei, Jian,Chen, Tieqiao,Zhou, Yongbo,Han, Li-Biao,Au, Chak-Tong,Yin, Shuang-Feng

, p. 4244 - 4247 (2014)

A copper-catalyzed system for the amidation of carboxylic acids with tert-amines through C-N bond cleavage was developed. This protocol is practical and represents a simple way to produce functionalized amides from basic starting materials in moderate to good yields. A plausible mechanism is proposed for the reaction.
