66253-25-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66253-25-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,5 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66253-25:
(7*6)+(6*6)+(5*2)+(4*5)+(3*3)+(2*2)+(1*5)=126
126 % 10 = 6
So 66253-25-6 is a valid CAS Registry Number.
