Check Digit Verification of cas no

The CAS Registry Mumber 199788-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,7,8 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 199788-67:
(8*1)+(7*9)+(6*9)+(5*7)+(4*8)+(3*8)+(2*6)+(1*7)=235
235 % 10 = 5
So 199788-67-5 is a valid CAS Registry Number.

, p. 1977 - 1981 (2020)

The electrochemical synthesis of N, N’-disubstituted benzimidazolones from ureas through an intramolecular anodic dehydrogenative N?H/C?H coupling has been developed. The reaction undergoes under the undivided electrolysis conditions and obviates the need for any catalysts and chemical oxidants. (Figure presented.).
