65341-21-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65341-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,3,4 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 65341-21:
(7*6)+(6*5)+(5*3)+(4*4)+(3*1)+(2*2)+(1*1)=111
111 % 10 = 1
So 65341-21-1 is a valid CAS Registry Number.
