Check Digit Verification of cas no

The CAS Registry Mumber 176445-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,4,4 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 176445-50:
(8*1)+(7*7)+(6*6)+(5*4)+(4*4)+(3*5)+(2*5)+(1*0)=154
154 % 10 = 4
So 176445-50-4 is a valid CAS Registry Number.
