89929-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89929-53-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,2 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89929-53:
(7*8)+(6*9)+(5*9)+(4*2)+(3*9)+(2*5)+(1*3)=203
203 % 10 = 3
So 89929-53-3 is a valid CAS Registry Number.
