Check Digit Verification of cas no
The CAS Registry Mumber 20215-36-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,1 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20215-36:
(7*2)+(6*0)+(5*2)+(4*1)+(3*5)+(2*3)+(1*6)=55
55 % 10 = 5
So 20215-36-5 is a valid CAS Registry Number.

Synthesis and Photochemistry of 1,2-Naphtoquinonediazide-(2)-n-sulfonic Acid Derivatives
Bendig, J.,Sauer, E.,Polz, K.,Schopf, G.,Koch, A.
, p. 9207 - 9216 (2007/10/02)
The 1,2-naphthoquinonediazide-(2)-6- and -7-sulfonic acid esters (7c, 7d) have been synthesized for first time starting from the 1-naphthyl-amine-6- and -7-sulfonic acids (1c, 1d), respectively, via Bucherer reaction, nitrosation, reduction, diazotation, sulfochlorination, esterification.The synthesis of the corresponding 8-sulfonic acid ester 7e was not successful by this way.On photolysis the 1,2-naphthoquinonediazide-(2)-6- and -7-sulfonic acid phenyl esters (7c, 7d) form the corresponding (phenoxysulfonyl)-indenecarboxylic acid (10c, 10d) in the same manner like the known 5-sulfonic acid 4-sulfonic acid ester 7a a photochemically induced ester cleavage occurs additionally (λ 320 nm).
