27249-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27249-72-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,2,4 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 27249-72:
(7*2)+(6*7)+(5*2)+(4*4)+(3*9)+(2*7)+(1*2)=125
125 % 10 = 5
So 27249-72-5 is a valid CAS Registry Number.
