Check Digit Verification of cas no

The CAS Registry Mumber 873542-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,5,4 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 873542-04:
(8*8)+(7*7)+(6*3)+(5*5)+(4*4)+(3*2)+(2*0)+(1*4)=182
182 % 10 = 2
So 873542-04-2 is a valid CAS Registry Number.

supporting information; experimental part, p. 3718 - 3722 (2011/08/06)

An enantioselective hydrogenation of hydrazones derived from heterocyclic ketones was developed with up to 85% ee. The enantiomeric purity was enriched to >99% ee by crystallization from EtOAc in >80% yield. Optimization studies have revealed a notable so
