Check Digit Verification of cas no

The CAS Registry Mumber 28743-95-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,4 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28743-95:
(7*2)+(6*8)+(5*7)+(4*4)+(3*3)+(2*9)+(1*5)=145
145 % 10 = 5
So 28743-95-5 is a valid CAS Registry Number.
