Check Digit Verification of cas no
The CAS Registry Mumber 134039-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,0,3 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134039-03:
(8*1)+(7*3)+(6*4)+(5*0)+(4*3)+(3*9)+(2*0)+(1*3)=95
95 % 10 = 5
So 134039-03-5 is a valid CAS Registry Number.
