133838-69-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133838-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,3 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133838-69:
(8*1)+(7*3)+(6*3)+(5*8)+(4*3)+(3*8)+(2*6)+(1*9)=144
144 % 10 = 4
So 133838-69-4 is a valid CAS Registry Number.

Synthesis, acidic and basic properties of thiols and sulfinic acids from the series of diphenyl bridging compounds

Alov,Nikiforov,Novikov,Kobylinskii,Moskvichev,Kryukova,Yasinskii,Budanov

, p. 1160 - 1164 (2007/10/03)

A series of dithiols and disulfinic acids belonging to diphenyl bridging compounds was prepared and identified. The conditions of reduction for the corresponding sulfonyl chlorides were optimized resulting in production of the target compounds in 85-95% yields. The acidity constants of the compounds obtained were measured. A correlation between pKa and δSH, was established for thiols. Therewith the dissociation constants of thiols are readily evaluated by the chemical shift of the thiol group proton.
