51775-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51775-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,7 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 51775-50:
(7*5)+(6*1)+(5*7)+(4*7)+(3*5)+(2*5)+(1*0)=129
129 % 10 = 9
So 51775-50-9 is a valid CAS Registry Number.
