Check Digit Verification of cas no

The CAS Registry Mumber 239447-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,9,4,4 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 239447-57:
(8*2)+(7*3)+(6*9)+(5*4)+(4*4)+(3*7)+(2*5)+(1*7)=165
165 % 10 = 5
So 239447-57-5 is a valid CAS Registry Number.
