443302-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 443302-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,3,3,0 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 443302-21:
(8*4)+(7*4)+(6*3)+(5*3)+(4*0)+(3*2)+(2*2)+(1*1)=104
104 % 10 = 4
So 443302-21-4 is a valid CAS Registry Number.
