57100-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57100-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,0 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57100-49:
(7*5)+(6*7)+(5*1)+(4*0)+(3*0)+(2*4)+(1*9)=99
99 % 10 = 9
So 57100-49-9 is a valid CAS Registry Number.
