51757-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51757-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,5 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 51757-49:
(7*5)+(6*1)+(5*7)+(4*5)+(3*7)+(2*4)+(1*9)=134
134 % 10 = 4
So 51757-49-4 is a valid CAS Registry Number.
