65848-43-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65848-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,4 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 65848-43:
(7*6)+(6*5)+(5*8)+(4*4)+(3*8)+(2*4)+(1*3)=163
163 % 10 = 3
So 65848-43-3 is a valid CAS Registry Number.
