97183-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97183-44-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,8 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 97183-44:
(7*9)+(6*7)+(5*1)+(4*8)+(3*3)+(2*4)+(1*4)=163
163 % 10 = 3
So 97183-44-3 is a valid CAS Registry Number.
