4921-71-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4921-71-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,2 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4921-71:
(6*4)+(5*9)+(4*2)+(3*1)+(2*7)+(1*1)=95
95 % 10 = 5
So 4921-71-5 is a valid CAS Registry Number.
