Check Digit Verification of cas no

The CAS Registry Mumber 7639-18-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,3 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7639-18:
(6*7)+(5*6)+(4*3)+(3*9)+(2*1)+(1*8)=121
121 % 10 = 1
So 7639-18-1 is a valid CAS Registry Number.
