Check Digit Verification of cas no

The CAS Registry Mumber 3990-19-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,9 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3990-19:
(6*3)+(5*9)+(4*9)+(3*0)+(2*1)+(1*9)=110
110 % 10 = 0
So 3990-19-0 is a valid CAS Registry Number.
