5099-01-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5099-01-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,9 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5099-01:
(6*5)+(5*0)+(4*9)+(3*9)+(2*0)+(1*1)=94
94 % 10 = 4
So 5099-01-4 is a valid CAS Registry Number.
