89435-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89435-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,3 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89435-81:
(7*8)+(6*9)+(5*4)+(4*3)+(3*5)+(2*8)+(1*1)=174
174 % 10 = 4
So 89435-81-4 is a valid CAS Registry Number.
