721922-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 721922-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,1,9,2 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 721922-74:
(8*7)+(7*2)+(6*1)+(5*9)+(4*2)+(3*2)+(2*7)+(1*4)=153
153 % 10 = 3
So 721922-74-3 is a valid CAS Registry Number.
