Check Digit Verification of cas no

The CAS Registry Mumber 1443309-03-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,3,0 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1443309-03:
(9*1)+(8*4)+(7*4)+(6*3)+(5*3)+(4*0)+(3*9)+(2*0)+(1*3)=132
132 % 10 = 2
So 1443309-03-2 is a valid CAS Registry Number.

Enantioselective iridium-catalyzed hydrogenation of 1- and 3-substituted isoquinolinium salts

Ye, Zhi-Shi,Guo, Ran-Ning,Cai, Xian-Feng,Chen, Mu-Wang,Shi, Lei,Zhou, Yong-Gui

supporting information, p. 3685 - 3689 (2013/04/24)

Asymmetric hydrogenation: The title reaction provides an efficient and rapid access to chiral 1- and 3-substituted 1,2,3,4-tetrahydroisoquinolines with excellent enantioselectivity (see scheme; L=ligand). A preliminary mechanistic study indicates that the 1,2-hydride addition might be the initial step in the reaction. The method has been used in the synthesis of urinary antispasmodic drug (+)-solifenacin. Copyright
