Check Digit Verification of cas no

The CAS Registry Mumber 66657-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66657-90:
(7*6)+(6*6)+(5*6)+(4*5)+(3*7)+(2*9)+(1*0)=167
167 % 10 = 7
So 66657-90-7 is a valid CAS Registry Number.
