Check Digit Verification of cas no

The CAS Registry Mumber 1338441-53-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,4,4 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1338441-53:
(9*1)+(8*3)+(7*3)+(6*8)+(5*4)+(4*4)+(3*1)+(2*5)+(1*3)=154
154 % 10 = 4
So 1338441-53-4 is a valid CAS Registry Number.

Synthesis of 2,4,6-trisubstituted pyridines via an olefin cross-metathesis/Heck-cyclisation-elimination sequence

Donohoe, Timothy J.,Bower, John F.,Baker, David B.,Basutto, Jose A.,Chan, Louis K. M.,Gallagher, Peter

supporting information; experimental part, p. 10611 - 10613 (2011/11/04)

Heck reactions were performed on α,β-unsaturated-δ- sulfonamido intermediates, derived from cross metathesis, to allow the instalment of substituents at the β position. Subsequent one-pot cyclisation/elimination provides an operationally simple, catalytic and convergent synthesis of 2,4,6-trisubstituted pyridines.
