26772-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26772-97-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,7 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26772-97:
(7*2)+(6*6)+(5*7)+(4*7)+(3*2)+(2*9)+(1*7)=144
144 % 10 = 4
So 26772-97-4 is a valid CAS Registry Number.
