Check Digit Verification of cas no

The CAS Registry Mumber 444901-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,9,0 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 444901-95:
(8*4)+(7*4)+(6*4)+(5*9)+(4*0)+(3*1)+(2*9)+(1*5)=155
155 % 10 = 5
So 444901-95-5 is a valid CAS Registry Number.

Facile synthesis of proline based phosphine-oxazoline ligands by formation of a P-N bond

Xu, Guopin,Gilbertson, Scott R

, p. 2811 - 2814 (2002)

A series of new P-N ligands in which the phosphorus moiety is introduced by formation of a phosphorus-heteroatom bond are synthesized. These ligands are based on proline with chiral centers from both proline and an oxazoline. The two chiral centers are re
