251353-58-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 251353-58-9 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, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 251353-58:
(8*2)+(7*5)+(6*1)+(5*3)+(4*5)+(3*3)+(2*5)+(1*8)=119
119 % 10 = 9
So 251353-58-9 is a valid CAS Registry Number.
