Check Digit Verification of cas no

The CAS Registry Mumber 7619-65-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,1 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7619-65:
(6*7)+(5*6)+(4*1)+(3*9)+(2*6)+(1*5)=120
120 % 10 = 0
So 7619-65-0 is a valid CAS Registry Number.
