Check Digit Verification of cas no

The CAS Registry Mumber 202201-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,2,0 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 202201-46:
(8*2)+(7*0)+(6*2)+(5*2)+(4*0)+(3*1)+(2*4)+(1*6)=55
55 % 10 = 5
So 202201-46-5 is a valid CAS Registry Number.
