51655-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51655-67-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,5 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51655-67:
(7*5)+(6*1)+(5*6)+(4*5)+(3*5)+(2*6)+(1*7)=125
125 % 10 = 5
So 51655-67-5 is a valid CAS Registry Number.
