Check Digit Verification of cas no

The CAS Registry Mumber 1223736-66-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,3,7,3 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1223736-66:
(9*1)+(8*2)+(7*2)+(6*3)+(5*7)+(4*3)+(3*6)+(2*6)+(1*6)=140
140 % 10 = 0
So 1223736-66-0 is a valid CAS Registry Number.

Synthesis of tetrahydro-β-carbolines via isomerization of N-allyltryptamines: A metal-catalyzed variation on the Pictet-Spengler theme

Ascic, Erhad,Hansen, Casper L.,Le Quement, Sebastian T.,Nielsen, Thomas E.

, p. 3345 - 3347 (2012/05/04)

An efficient and broadly applicable alternative to the classical Pictet-Spengler synthesis of tetrahydro-β-carbolines is presented. The method relies on metal-catalyzed isomerization of allylic amines to form reactive iminium intermediates which can be trapped by a tethered indole nucleophile.
