Check Digit Verification of cas no

The CAS Registry Mumber 57642-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,4 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57642-26:
(7*5)+(6*7)+(5*6)+(4*4)+(3*2)+(2*2)+(1*6)=139
139 % 10 = 9
So 57642-26-9 is a valid CAS Registry Number.

, p. 11976 - 11980 (2017)

A new class of palladium catalysts, based on heterocyclic diphosphines, was rationally designed and synthesized. Application of one of these catalysts allows novel Markovnikov-selective carbonylation of non-activated alkynes with heteroarenes to give the
