Check Digit Verification of cas no

The CAS Registry Mumber 856454-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,4,5 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 856454-50:
(8*8)+(7*5)+(6*6)+(5*4)+(4*5)+(3*4)+(2*5)+(1*0)=197
197 % 10 = 7
So 856454-50-7 is a valid CAS Registry Number.
