Check Digit Verification of cas no

The CAS Registry Mumber 60041-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,0,4 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 60041-99:
(7*6)+(6*0)+(5*0)+(4*4)+(3*1)+(2*9)+(1*9)=88
88 % 10 = 8
So 60041-99-8 is a valid CAS Registry Number.

NaNO2/I2 as an alternative reagent for the synthesis of 1,2,3-benzotriazin-4(3H)-ones from 2-aminobenzamides

Barak, Dinesh S.,Mukhopadhyay, Sushobhan,Dahatonde, Dipak J.,Batra, Sanjay

, p. 248 - 251 (2019)

An efficient transformation of 2-aminobenzamides to 1,2,3-benzotriazin-4(3H)-ones in the presence of sodium nitrite (NaNO2) and Iodine (I2) is described. The reaction is proposed to proceed via formation of nitrosyl halide that induces nitrosylation of the amino group of 2-aminobenzamide leading to diazotization followed by intramolecular cyclization.
