Check Digit Verification of cas no

The CAS Registry Mumber 119099-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,9 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119099-51:
(8*1)+(7*1)+(6*9)+(5*0)+(4*9)+(3*9)+(2*5)+(1*1)=143
143 % 10 = 3
So 119099-51-3 is a valid CAS Registry Number.

Formation of a PIII-C(sp2) bond by addition of diphenyl(trimethylsilyl)phosphine to activated acetylenes

Kochetkov,Efimova,Trostyanskaya,Kazankova,Beletskaya

, p. 1744 - 1748 (1998)

Diphenyl(trimethylsilyl)phosphine reacts with alkoxy(alkyl)acetylenes to give mixtures of addition products, (2-alkoxy-2-trimethylsilylalkenyl)diphenylphosphines and (2-alkoxyalkenyl)diphenylphosphines. The reaction is sensitive to the solvent; in MeCN, it gives only nonsilylated products. (1-Alkoxyethenyl)diphenylphosphines were obtained as the main products upon the reaction of Ph2PSiMe3 with terminal alkoxyalkynes, irrespective of the reaction conditions.
