4991-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4991-55-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 4991-55:
(6*4)+(5*9)+(4*9)+(3*1)+(2*5)+(1*5)=123
123 % 10 = 3
So 4991-55-3 is a valid CAS Registry Number.
