Check Digit Verification of cas no

The CAS Registry Mumber 190144-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,1,4 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 190144-08:
(8*1)+(7*9)+(6*0)+(5*1)+(4*4)+(3*4)+(2*0)+(1*8)=112
112 % 10 = 2
So 190144-08-2 is a valid CAS Registry Number.

Synthesis of new C2-symmetrical diphosphines using chiral zinc organometallics

Longeau, Alexia,Durand, Sandrine,Spiegel, Anja,Knoechel, Paul

, p. 987 - 990 (1997)

The new C2-symmetrical diphosphines 1-4 of potential interest for asymmetric catalysis were prepared in protected form by a convergent synthesis based on the use of readily available (S,S)-1,2-cyclohexanedicarboxylic acid 8 and the phosphorus reagent (Et2N)2PLi·BH3.
