349147-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 349147-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,1,4 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 349147-89:
(8*3)+(7*4)+(6*9)+(5*1)+(4*4)+(3*7)+(2*8)+(1*9)=173
173 % 10 = 3
So 349147-89-3 is a valid CAS Registry Number.

Facile synthesis of (R)-4-mercaptopyrrolidine-2-thione from l-aspartic acid
Seki, Masahiko,Shimizu, Toshiaki
, p. 973 - 976 (2007/10/03)
An SN2-type of substitution of (S)-bromide 4, which had been prepared from L-aspartic acid, with potassium thiobenzoate provided (R)-benzoylthio derivative 5 with complete inversion of the configuration. Compound 5 was converted, via iodide 6c, to (R)-4-a
