Check Digit Verification of cas no

The CAS Registry Mumber 15533-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,3 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15533-33:
(7*1)+(6*5)+(5*5)+(4*3)+(3*3)+(2*3)+(1*3)=92
92 % 10 = 2
So 15533-33-2 is a valid CAS Registry Number.

S-(HYDROXYMETHYL) 4-HYDROXYPHENYL SULFIDES: SYNTHESIS AND SELECTED CHEMISTRY OF SOME STABLE HEMIMERCAPTALS

Pastor, Stephen D.,Odorisio, Paul A.,Ravichandran, Ramanathan

, p. 67 - 72 (2007/10/02)

The base-catalyzed reaction of 3,5-di-tert-butyl-4-hydroxybenzenethiol (1a), 3-tert-butyl-4-hydroxy-5-methylbenzenethiol (1b), and 4-hydroxybenzenethiol (1c) with formaldehyde gave the corresponding hemimercaptal derivatives 2a-c, respectively.The stable hemimercaptals 2a-c were characterized by IR, 1H NMR, 13C NMR, MS and elemental analysis.The ester of 2a with 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoic acid (3a) was prepared using triphenylphosphine and diethyl azodicarboxylate (Mitsunobu conditions).
