Check Digit Verification of cas no

The CAS Registry Mumber 6703-90-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,0 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6703-90:
(6*6)+(5*7)+(4*0)+(3*3)+(2*9)+(1*0)=98
98 % 10 = 8
So 6703-90-8 is a valid CAS Registry Number.
