138650-56-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138650-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,5 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138650-56:
(8*1)+(7*3)+(6*8)+(5*6)+(4*5)+(3*0)+(2*5)+(1*6)=143
143 % 10 = 3
So 138650-56-3 is a valid CAS Registry Number.

A facile general synthesis of thiocarboxylate S-esters of glyphosphate and its derivatives
Mao,Franz
, p. 920 - 922 (1991)
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
