Check Digit Verification of cas no

The CAS Registry Mumber 1556678-54-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,6,6,7 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1556678-54:
(9*1)+(8*5)+(7*5)+(6*6)+(5*6)+(4*7)+(3*8)+(2*5)+(1*4)=216
216 % 10 = 6
So 1556678-54-6 is a valid CAS Registry Number.

, p. 2145 - 2147 (2014/02/14)

A silver catalysed synthesis of 6-acyl phenanthridines by oxidative radical decarboxylation-cyclization of α-oxocarboxylates and isocyanides was developed. This reaction provided a novel method to realize C1 insertion via a radical process and various functional groups were well-tolerated. The Royal Society of Chemistry.
