89663-04-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89663-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,6 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89663-04:
(7*8)+(6*9)+(5*6)+(4*6)+(3*3)+(2*0)+(1*4)=177
177 % 10 = 7
So 89663-04-7 is a valid CAS Registry Number.
