Check Digit Verification of cas no

The CAS Registry Mumber 81542-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,4 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81542-34:
(7*8)+(6*1)+(5*5)+(4*4)+(3*2)+(2*3)+(1*4)=119
119 % 10 = 9
So 81542-34-9 is a valid CAS Registry Number.

Enantioselective Cu-Catalyzed Arylation of Secondary Phosphine Oxides with Diaryliodonium Salts toward the Synthesis of P-Chiral Phosphines

Beaud, Rodolphe,Phipps, Robert J.,Gaunt, Matthew J.

, p. 13183 - 13186 (2016/10/22)

Catalytic synthesis of nonracemic P-chiral phosphine derivatives remains a significant challenge. Here we report Cu-catalyzed enantioselective arylation of secondary phosphine oxides with diaryliodonium salts for the synthesis of tertiary phosphine oxides
