51117-67-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51117-67-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,1,1 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51117-67:
(7*5)+(6*1)+(5*1)+(4*1)+(3*7)+(2*6)+(1*7)=90
90 % 10 = 0
So 51117-67-0 is a valid CAS Registry Number.
