21278-45-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21278-45-5 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 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21278-45:
(7*2)+(6*1)+(5*2)+(4*7)+(3*8)+(2*4)+(1*5)=95
95 % 10 = 5
So 21278-45-5 is a valid CAS Registry Number.
