Check Digit Verification of cas no

The CAS Registry Mumber 667923-56-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,7,9,2 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 667923-56:
(8*6)+(7*6)+(6*7)+(5*9)+(4*2)+(3*3)+(2*5)+(1*6)=210
210 % 10 = 0
So 667923-56-0 is a valid CAS Registry Number.
