Check Digit Verification of cas no

The CAS Registry Mumber 1346176-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,1,7 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1346176-91:
(9*1)+(8*3)+(7*4)+(6*6)+(5*1)+(4*7)+(3*6)+(2*9)+(1*1)=167
167 % 10 = 7
So 1346176-91-7 is a valid CAS Registry Number.

Phase-transfer-catalyzed asymmetric synthesis of 1,1-disubstituted tetrahydroisoquinolines

Shirakawa, Seiji,Liu, Kun,Ito, Hironobu,Le, Thanh Nguyen,Maruoka, Keiji

supporting information; experimental part, p. 2614 - 2618 (2011/11/29)

A highly efficient catalytic asymmetric synthesis of 1,1-disubstituted tetrahydroisoquinolines has been achieved via asymmetric alkylation or Michael addition of 1-cyanotetrahydroisoquinolines using binaphthyl-modified N-spiro-type chiral phase-transfer c
