Check Digit Verification of cas no

The CAS Registry Mumber 41902-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,9,0 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 41902-21:
(7*4)+(6*1)+(5*9)+(4*0)+(3*2)+(2*2)+(1*1)=90
90 % 10 = 0
So 41902-21-0 is a valid CAS Registry Number.
