70562-38-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70562-38-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,6 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 70562-38:
(7*7)+(6*0)+(5*5)+(4*6)+(3*2)+(2*3)+(1*8)=118
118 % 10 = 8
So 70562-38-8 is a valid CAS Registry Number.

Novel palladium-catalyzed thiophosphorylation of alkynes with phosphorethioate: An efficient route to (Z)-1-(diphenoxyphosphinyl)-2-(phenylthio)alkenes

Han, Li-Biao,Tanaka, Masato

, p. 863 - 864 (1999)

Palladium complexes efficiently catalyze the addition of O,O,S-triphenyl phosphorothioate to terminal alkynes to produce (Z)-1-(diphenoxyphosphinyl)-2-(phenylthio)alkenes in high yields with high regio- and stereoselectivity.
