Check Digit Verification of cas no

The CAS Registry Mumber 220765-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,7,6 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220765-73:
(8*2)+(7*2)+(6*0)+(5*7)+(4*6)+(3*5)+(2*7)+(1*3)=121
121 % 10 = 1
So 220765-73-1 is a valid CAS Registry Number.
