Check Digit Verification of cas no

The CAS Registry Mumber 111155-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,5 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 111155-56:
(8*1)+(7*1)+(6*1)+(5*1)+(4*5)+(3*5)+(2*5)+(1*6)=77
77 % 10 = 7
So 111155-56-7 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).
