Check Digit Verification of cas no

The CAS Registry Mumber 1373052-15-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,0,5 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1373052-15:
(9*1)+(8*3)+(7*7)+(6*3)+(5*0)+(4*5)+(3*2)+(2*1)+(1*5)=133
133 % 10 = 3
So 1373052-15-3 is a valid CAS Registry Number.

Phosphine-boronates: Efficient bifunctional organocatalysts for Michael addition

Basle, Olivier,Porcel, Susana,Ladeira, Sonia,Bouhadir, Ghenwa,Bourissou, Didier

supporting information; experimental part, p. 4495 - 4497 (2012/05/31)

Phosphine-boronates R2P(o-C6H4) B(OR′)2 have been evaluated as bifunctional organocatalysts for the Michael addition of malonate pronucleophiles to methylvinylketone. The presence of the Lewis acidic boron center adjacent to phosphorus significantly improves catalytic performance. Isolation and complete characterization of a key intermediate, namely a β-phosphonium enolate, substantiate the role of the Lewis acidic moiety in the catalytic process.
