Check Digit Verification of cas no

The CAS Registry Mumber 861239-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,2,3 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 861239-99:
(8*8)+(7*6)+(6*1)+(5*2)+(4*3)+(3*9)+(2*9)+(1*9)=188
188 % 10 = 8
So 861239-99-8 is a valid CAS Registry Number.

A convenient synthesis of N-aryl benzamides by rhodium-catalyzed ortho-amidation and decarboxylation of benzoic acids

Shi, Xian-Ying,Liu, Ke-Yan,Fan, Juan,Dong, Xue-Fen,Wei, Jun-Fa,Li, Chao-Jun

, p. 1900 - 1903 (2015)

The rhodium-catalyzed amidation of substituted benzoic acids with isocyanates by directed C-H functionalization followed by decarboxylation to afford the corresponding N-aryl benzamides is demonstrated, in which the carboxylate serves as a unique, removable directing group. Notably, less common meta-substituted N-aryl benzamides are generated readily from more accessible paraor ortho-substituted groups by employing this strategy.
