Check Digit Verification of cas no

The CAS Registry Mumber 278600-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,8,6,0 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 278600-44:
(8*2)+(7*7)+(6*8)+(5*6)+(4*0)+(3*0)+(2*4)+(1*4)=155
155 % 10 = 5
So 278600-44-5 is a valid CAS Registry Number.
