Check Digit Verification of cas no
The CAS Registry Mumber 4391-99-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4391-99:
(6*4)+(5*3)+(4*9)+(3*1)+(2*9)+(1*9)=105
105 % 10 = 5
So 4391-99-5 is a valid CAS Registry Number.
