Check Digit Verification of cas no

The CAS Registry Mumber 137776-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,7 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137776-56:
(8*1)+(7*3)+(6*7)+(5*7)+(4*7)+(3*6)+(2*5)+(1*6)=168
168 % 10 = 8
So 137776-56-8 is a valid CAS Registry Number.
