Check Digit Verification of cas no

The CAS Registry Mumber 1646906-19-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,6,9,0 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1646906-19:
(9*1)+(8*6)+(7*4)+(6*6)+(5*9)+(4*0)+(3*6)+(2*1)+(1*9)=195
195 % 10 = 5
So 1646906-19-5 is a valid CAS Registry Number.
