Check Digit Verification of cas no

The CAS Registry Mumber 381725-24-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,1,7,2 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 381725-24:
(8*3)+(7*8)+(6*1)+(5*7)+(4*2)+(3*5)+(2*2)+(1*4)=152
152 % 10 = 2
So 381725-24-2 is a valid CAS Registry Number.
