68558-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 68558-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,5 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68558-89:
(7*6)+(6*8)+(5*5)+(4*5)+(3*8)+(2*8)+(1*9)=184
184 % 10 = 4
So 68558-89-4 is a valid CAS Registry Number.
