Check Digit Verification of cas no

The CAS Registry Mumber 946-22-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 946-22:
(5*9)+(4*4)+(3*6)+(2*2)+(1*2)=85
85 % 10 = 5
So 946-22-5 is a valid CAS Registry Number.
