Check Digit Verification of cas no

The CAS Registry Mumber 187975-72-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,9,7 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 187975-72:
(8*1)+(7*8)+(6*7)+(5*9)+(4*7)+(3*5)+(2*7)+(1*2)=210
210 % 10 = 0
So 187975-72-0 is a valid CAS Registry Number.

A convenient (E)-stereoselective synthesis of alkenylphosphonates

Truel, Isabelle,Mohamed-Hachi, Abdourahman,About-Jaudet, Elie,Collignon, Noel

, p. 297 - 302 (1997)

Diethyl (E)-alkenylphosphonates have been prepared stereoselectively by dehydration of the corresponding β-hydroxyphosphonates using DCC/CuCl2 in refluxing toluene. Starting β-hydroxyphosphonates were obtained in high yield from diethyl methylphosphonate.
