4997-55-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4997-55-1 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 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4997-55:
(6*4)+(5*9)+(4*9)+(3*7)+(2*5)+(1*5)=141
141 % 10 = 1
So 4997-55-1 is a valid CAS Registry Number.
