2726-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2726-54-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,2 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2726-54:
(6*2)+(5*7)+(4*2)+(3*6)+(2*5)+(1*4)=87
87 % 10 = 7
So 2726-54-7 is a valid CAS Registry Number.
