Check Digit Verification of cas no

The CAS Registry Mumber 252756-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,7,5 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 252756-49:
(8*2)+(7*5)+(6*2)+(5*7)+(4*5)+(3*6)+(2*4)+(1*9)=153
153 % 10 = 3
So 252756-49-3 is a valid CAS Registry Number.
