Check Digit Verification of cas no

The CAS Registry Mumber 1254076-21-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,0,7 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1254076-21:
(9*1)+(8*2)+(7*5)+(6*4)+(5*0)+(4*7)+(3*6)+(2*2)+(1*1)=135
135 % 10 = 5
So 1254076-21-5 is a valid CAS Registry Number.

Scaled-up transition-metal-catalyzed cross-coupling reactions of thioether-substituted N-heterocycles with organozinc reagents

Metzger, Albrecht,Melzig, Laurin,Knochel, Paul

, p. 2853 - 2858 (2010)

A variety of functionalized methylthio-substituted N-heterocycles (pyridines, pyrimidines, pyrazines, pyridazines, triazines, quinazolines, benzothiazoles) undergo smooth palladium- or nickel-catalyzed cross-couplings with highly functionalized organozinc reagents at ambient temperature. No expensive copper(I) salts are required and the coupling reactions proceed readily in the range of up to 20 mmol scale. Georg Thieme Verlag Stuttgart.
