Check Digit Verification of cas no

The CAS Registry Mumber 856906-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,9,0 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 856906-97:
(8*8)+(7*5)+(6*6)+(5*9)+(4*0)+(3*6)+(2*9)+(1*7)=223
223 % 10 = 3
So 856906-97-3 is a valid CAS Registry Number.
