Check Digit Verification of cas no
The CAS Registry Mumber 53992-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,9 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 53992-33:
(7*5)+(6*3)+(5*9)+(4*9)+(3*2)+(2*3)+(1*3)=149
149 % 10 = 9
So 53992-33-9 is a valid CAS Registry Number.

Synthesis of 5-substituted indole derivatives. Part 3: A facile synthesis of 5-chloromethyl-1H-indole-2-carboxylates: Replacement of sulfonic acid functionality by chlorine
Pete, Béla,Toke, László
, p. 3373 - 3375 (2001)
Valuable new synthetic intermediates, 5-chloromethyl-1H-indole-2-carboxylates, were prepared by the elimination of SO2 from 2-ethoxycarbonyl-1H-indole-5-methanesulfonic acids, which are easily accessible by Fischer-type indolization.
