Check Digit Verification of cas no

The CAS Registry Mumber 90842-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,4 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90842-90:
(7*9)+(6*0)+(5*8)+(4*4)+(3*2)+(2*9)+(1*0)=143
143 % 10 = 3
So 90842-90-3 is a valid CAS Registry Number.
