552888-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 552888-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,2,8,8 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 552888-93:
(8*5)+(7*5)+(6*2)+(5*8)+(4*8)+(3*8)+(2*9)+(1*3)=204
204 % 10 = 4
So 552888-93-4 is a valid CAS Registry Number.
