253797-62-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 253797-62-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,7,9 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 253797-62:
(8*2)+(7*5)+(6*3)+(5*7)+(4*9)+(3*7)+(2*6)+(1*2)=175
175 % 10 = 5
So 253797-62-5 is a valid CAS Registry Number.
