Check Digit Verification of cas no

The CAS Registry Mumber 18351-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,5 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18351-70:
(7*1)+(6*8)+(5*3)+(4*5)+(3*1)+(2*7)+(1*0)=107
107 % 10 = 7
So 18351-70-7 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.

supporting information, 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
