Check Digit Verification of cas no

The CAS Registry Mumber 6226-91-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6226-91:
(6*6)+(5*2)+(4*2)+(3*6)+(2*9)+(1*1)=91
91 % 10 = 1
So 6226-91-1 is a valid CAS Registry Number.
