51570-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51570-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,7 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 51570-89:
(7*5)+(6*1)+(5*5)+(4*7)+(3*0)+(2*8)+(1*9)=119
119 % 10 = 9
So 51570-89-9 is a valid CAS Registry Number.
