Check Digit Verification of cas no

The CAS Registry Mumber 223397-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,3,9 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 223397-73:
(8*2)+(7*2)+(6*3)+(5*3)+(4*9)+(3*7)+(2*7)+(1*3)=137
137 % 10 = 7
So 223397-73-7 is a valid CAS Registry Number.
