Check Digit Verification of cas no

The CAS Registry Mumber 253170-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,1,7 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 253170-47:
(8*2)+(7*5)+(6*3)+(5*1)+(4*7)+(3*0)+(2*4)+(1*7)=117
117 % 10 = 7
So 253170-47-7 is a valid CAS Registry Number.
