Check Digit Verification of cas no

The CAS Registry Mumber 156387-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,3,8 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156387-49:
(8*1)+(7*5)+(6*6)+(5*3)+(4*8)+(3*7)+(2*4)+(1*9)=164
164 % 10 = 4
So 156387-49-4 is a valid CAS Registry Number.
