Check Digit Verification of cas no

The CAS Registry Mumber 1198617-03-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,6,1 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1198617-03:
(9*1)+(8*1)+(7*9)+(6*8)+(5*6)+(4*1)+(3*7)+(2*0)+(1*3)=186
186 % 10 = 6
So 1198617-03-6 is a valid CAS Registry Number.

Convenient synthesis of tropos phosphine-oxazoline ligands

Liu, Yuanyuan,Yang, Guoqiang,Yao, Dongmei,Tian, Fengtao,Zhang, Wanbin

experimental part, p. 87 - 94 (2011/12/15)

Tropos phosphine-oxazoline ligands have shown interesting coordination behavior and excellent chiral inducing ability in asymmetry catalysis. Here we present a convenient and economic route for the synthesis of this type of ligands. According to this new route, the ligands with different electronic and steric properties have been prepared successfully.
