Check Digit Verification of cas no

The CAS Registry Mumber 90270-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,7 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90270-02:
(7*9)+(6*0)+(5*2)+(4*7)+(3*0)+(2*0)+(1*2)=103
103 % 10 = 3
So 90270-02-3 is a valid CAS Registry Number.
