Check Digit Verification of cas no
The CAS Registry Mumber 4519-39-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,1 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4519-39:
(6*4)+(5*5)+(4*1)+(3*9)+(2*3)+(1*9)=95
95 % 10 = 5
So 4519-39-5 is a valid CAS Registry Number.
