Check Digit Verification of cas no

The CAS Registry Mumber 222723-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,7,2 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 222723-63:
(8*2)+(7*2)+(6*2)+(5*7)+(4*2)+(3*3)+(2*6)+(1*3)=109
109 % 10 = 9
So 222723-63-9 is a valid CAS Registry Number.
