Check Digit Verification of cas no

The CAS Registry Mumber 7770-21-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7770-21:
(6*7)+(5*7)+(4*7)+(3*0)+(2*2)+(1*1)=110
110 % 10 = 0
So 7770-21-0 is a valid CAS Registry Number.
