89964-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89964-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,6 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89964-70:
(7*8)+(6*9)+(5*9)+(4*6)+(3*4)+(2*7)+(1*0)=205
205 % 10 = 5
So 89964-70-5 is a valid CAS Registry Number.
