556810-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 556810-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,6,8,1 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 556810-25:
(8*5)+(7*5)+(6*6)+(5*8)+(4*1)+(3*0)+(2*2)+(1*5)=164
164 % 10 = 4
So 556810-25-4 is a valid CAS Registry Number.
