Check Digit Verification of cas no

The CAS Registry Mumber 234089-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,4,0,8 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 234089-53:
(8*2)+(7*3)+(6*4)+(5*0)+(4*8)+(3*9)+(2*5)+(1*3)=133
133 % 10 = 3
So 234089-53-3 is a valid CAS Registry Number.

A new general method for the asymmetric synthesis of 4-alkyl-3-aryl- 1,2,3,4-tetrahydroisoquinolines

Vicario, Jose L.,Badia, Dolores,Dominguez, Esther,Carrillo, Luisa

, p. 4610 - 4616 (2007/10/03)

A highly enantioselective method for the synthesis of 4-alkyl substituted 1,2,3,4-tetrahydroisoquinolines is reported. The key step relies on the asymmetric synthesis of α-alkylarylacetic acids by alkylation of their corresponding amides employing (S,S)-(+)-pseudoephedrine as chiral inductor. Subsequent Friedel-Crafts acylation, stereocontrolled reductive amination and Pictet-Spengler cyclization affords the title compounds in excellent yields and enantioselectivities.
