253597-78-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 253597-78-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,5,9 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 253597-78:
(8*2)+(7*5)+(6*3)+(5*5)+(4*9)+(3*7)+(2*7)+(1*8)=173
173 % 10 = 3
So 253597-78-3 is a valid CAS Registry Number.
