Check Digit Verification of cas no

The CAS Registry Mumber 90626-28-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,2 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90626-28:
(7*9)+(6*0)+(5*6)+(4*2)+(3*6)+(2*2)+(1*8)=131
131 % 10 = 1
So 90626-28-1 is a valid CAS Registry Number.
