Check Digit Verification of cas no

The CAS Registry Mumber 1571105-24-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,1,1,0 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1571105-24:
(9*1)+(8*5)+(7*7)+(6*1)+(5*1)+(4*0)+(3*5)+(2*2)+(1*4)=132
132 % 10 = 2
So 1571105-24-2 is a valid CAS Registry Number.

Copper-catalyzed synthesis of 1,3-butadienylphosphine oxides and chemoselective phosphoryl reduction to stereodefined 1,3-butadienylphosphines

Gatignol, Jérémie,Alayrac, Carole,Lohier, Jean-Fran?ois,Ballester, Jorge,Taillefer, Marc,Gaumont, Annie-Claude

, p. 2822 - 2826 (2013)

Copper-catalyzed CP cross-coupling reactions between diphenylphosphine oxide and various 1-bromo-1,3-butadienes readily provided a set of functionalized 1,3-butadienyldiphenylphosphine oxides. Application of the latter to the synthesis of stereodefined 1,3-butadienyldiphenylphosphines was successfully achieved via chemoselective reduction of their phosphoryl moiety.
