Check Digit Verification of cas no

The CAS Registry Mumber 97100-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,0 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97100-20:
(7*9)+(6*7)+(5*1)+(4*0)+(3*0)+(2*2)+(1*0)=114
114 % 10 = 4
So 97100-20-4 is a valid CAS Registry Number.
