Check Digit Verification of cas no

The CAS Registry Mumber 2219-55-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,1 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2219-55:
(6*2)+(5*2)+(4*1)+(3*9)+(2*5)+(1*5)=68
68 % 10 = 8
So 2219-55-8 is a valid CAS Registry Number.
