96347-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 96347-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,3,4 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 96347-28:
(7*9)+(6*6)+(5*3)+(4*4)+(3*7)+(2*2)+(1*8)=163
163 % 10 = 3
So 96347-28-3 is a valid CAS Registry Number.
