25144-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25144-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,4 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25144-50:
(7*2)+(6*5)+(5*1)+(4*4)+(3*4)+(2*5)+(1*0)=87
87 % 10 = 7
So 25144-50-7 is a valid CAS Registry Number.
