98491-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98491-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,9 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98491-44:
(7*9)+(6*8)+(5*4)+(4*9)+(3*1)+(2*4)+(1*4)=182
182 % 10 = 2
So 98491-44-2 is a valid CAS Registry Number.

A facile general synthesis of thiocarboxylate S-esters of glyphosphate and its derivatives
Mao,Franz
, p. 920 - 922 (2007/10/02)
Various glyphosate thiocarboxylate S-ester derivatives, e.g. S-alkyl 2-(phosphonomethylamino)ethanethioates and S-alkyl 2[(phenoxyphosphorylmethyl)amino]ethanethioates, are readily synthesized from N-benzyloxycarbonylglycine using N-methylene-tert-butylam
