633302-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 633302-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,3,3,0 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 633302-55:
(8*6)+(7*3)+(6*3)+(5*3)+(4*0)+(3*2)+(2*5)+(1*5)=123
123 % 10 = 3
So 633302-55-3 is a valid CAS Registry Number.
