Check Digit Verification of cas no

The CAS Registry Mumber 74819-56-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,1 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74819-56:
(7*7)+(6*4)+(5*8)+(4*1)+(3*9)+(2*5)+(1*6)=160
160 % 10 = 0
So 74819-56-0 is a valid CAS Registry Number.
