Check Digit Verification of cas no
The CAS Registry Mumber 128595-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,9 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128595-03:
(8*1)+(7*2)+(6*8)+(5*5)+(4*9)+(3*5)+(2*0)+(1*3)=149
149 % 10 = 9
So 128595-03-9 is a valid CAS Registry Number.
