21276-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21276-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,7 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21276-23:
(7*2)+(6*1)+(5*2)+(4*7)+(3*6)+(2*2)+(1*3)=83
83 % 10 = 3
So 21276-23-3 is a valid CAS Registry Number.
