23722-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23722-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,7,2 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 23722-28:
(7*2)+(6*3)+(5*7)+(4*2)+(3*2)+(2*2)+(1*8)=93
93 % 10 = 3
So 23722-28-3 is a valid CAS Registry Number.
