251353-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 251353-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,3,5 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 251353-66:
(8*2)+(7*5)+(6*1)+(5*3)+(4*5)+(3*3)+(2*6)+(1*6)=119
119 % 10 = 9
So 251353-66-9 is a valid CAS Registry Number.
