Check Digit Verification of cas no
The CAS Registry Mumber 154469-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,4,6 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 154469-89:
(8*1)+(7*5)+(6*4)+(5*4)+(4*6)+(3*9)+(2*8)+(1*9)=163
163 % 10 = 3
So 154469-89-3 is a valid CAS Registry Number.

Synthesis of [35S]phosphorothionate insecticides: The example of [35S]fenthion
Dias,Mornet,Kotoujansky
, p. 73 - 78 (1994)
A general method for the synthesis of [35S]phosphorothionates is proposed, based on the example of [35S]fenthion. This consists of reacting molecular 35S with the corresponding phosphites which are easily prepared from commercial precursors.
