98664-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98664-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,6 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 98664-97:
(7*9)+(6*8)+(5*6)+(4*6)+(3*4)+(2*9)+(1*7)=202
202 % 10 = 2
So 98664-97-2 is a valid CAS Registry Number.
