89868-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89868-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,6 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89868-22:
(7*8)+(6*9)+(5*8)+(4*6)+(3*8)+(2*2)+(1*2)=204
204 % 10 = 4
So 89868-22-4 is a valid CAS Registry Number.
