Check Digit Verification of cas no

The CAS Registry Mumber 138116-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,1 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138116-16:
(8*1)+(7*3)+(6*8)+(5*1)+(4*1)+(3*6)+(2*1)+(1*6)=112
112 % 10 = 2
So 138116-16-2 is a valid CAS Registry Number.

Phosphonates and phosphine oxides as reagents in a one-pot synthesis of coumarins

Bouyssou,Chenault

, p. 5341 - 5344 (2007/10/02)

Diethyl coumarin-3-phosphonates and Diphenyl coumarin-3-phosphinyloxide are obtained in mild conditions in one step, from acetoxysalicylaldehydes and triethyl phosphonoacetate or diphenyl phosphinyloxide acetate, by the use of a liquid/liquid phase transfer porcess without catalysor.
