Check Digit Verification of cas no

The CAS Registry Mumber 50277-02-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,2,7 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 50277-02:
(7*5)+(6*0)+(5*2)+(4*7)+(3*7)+(2*0)+(1*2)=96
96 % 10 = 6
So 50277-02-6 is a valid CAS Registry Number.
