Check Digit Verification of cas no

The CAS Registry Mumber 2940-22-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,4 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2940-22:
(6*2)+(5*9)+(4*4)+(3*0)+(2*2)+(1*2)=79
79 % 10 = 9
So 2940-22-9 is a valid CAS Registry Number.
