253143-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 253143-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,1,4 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 253143-34:
(8*2)+(7*5)+(6*3)+(5*1)+(4*4)+(3*3)+(2*3)+(1*4)=109
109 % 10 = 9
So 253143-34-9 is a valid CAS Registry Number.
