134281-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134281-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,8 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134281-48:
(8*1)+(7*3)+(6*4)+(5*2)+(4*8)+(3*1)+(2*4)+(1*8)=114
114 % 10 = 4
So 134281-48-4 is a valid CAS Registry Number.

Electrooxidative C-S cleavages as a neutral deprotection for carbocxylic acids
Kimura,Matsubara,Yamamoto,Sawaki
, p. 867 - 876 (1991)
C-S Bond cleavages of S-t-butyl thioates (1) and 4-methoxyphenylthiomethyl esters (2) are achieved electrochemically in an indirect and direct manner, respectively, in aqueous acetonitrile, affording an efficient method for deprotection of carboxylic acids under neutral conditions.
