Check Digit Verification of cas no

The CAS Registry Mumber 21850-34-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,5 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21850-34:
(7*2)+(6*1)+(5*8)+(4*5)+(3*0)+(2*3)+(1*4)=90
90 % 10 = 0
So 21850-34-0 is a valid CAS Registry Number.
