Check Digit Verification of cas no

The CAS Registry Mumber 848249-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,8,2,4 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 848249-78:
(8*8)+(7*4)+(6*8)+(5*2)+(4*4)+(3*9)+(2*7)+(1*8)=215
215 % 10 = 5
So 848249-78-5 is a valid CAS Registry Number.
