Check Digit Verification of cas no

The CAS Registry Mumber 90116-36-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,1 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90116-36:
(7*9)+(6*0)+(5*1)+(4*1)+(3*6)+(2*3)+(1*6)=102
102 % 10 = 2
So 90116-36-2 is a valid CAS Registry Number.

Ultrasound assisted diazotization and diazo coupling reactions using trichlorotriazine

Fekri, Leila Zare,Nikpassand, Mohammad

, p. 1629 - 1633 (2014)

A high rate and efficient procedure for the synthesis of azo dyes has been developed. This concluded the sequential diazotization-diazo condensation of aromatic amines such as 4,4'-sulfonyldianiline with NaNO2, or trichlorotriazine with couplin
