293328-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 293328-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,3,3,2 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 293328-91:
(8*2)+(7*9)+(6*3)+(5*3)+(4*2)+(3*8)+(2*9)+(1*1)=163
163 % 10 = 3
So 293328-91-3 is a valid CAS Registry Number.
