Check Digit Verification of cas no

The CAS Registry Mumber 147749-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,7,4 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 147749-71:
(8*1)+(7*4)+(6*7)+(5*7)+(4*4)+(3*9)+(2*7)+(1*1)=171
171 % 10 = 1
So 147749-71-1 is a valid CAS Registry Number.

, p. 1017 - 1024 (2007/10/02)

Trans-3,4-substituted 1,2,3,4-tetrahydroisoquinolin-4-ols were prepared diastereoselectively by an insertion reaction with zerovalent nickel and by Barbier reaction with butyllithium of N-(2-iodobenzyl)phenacylamines. The isoquinolin-4-ols were resolved by means of HPLC method and the absolute configurations were determined.
