26271-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26271-55-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,2,7 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26271-55:
(7*2)+(6*6)+(5*2)+(4*7)+(3*1)+(2*5)+(1*5)=106
106 % 10 = 6
So 26271-55-6 is a valid CAS Registry Number.
