72302-56-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72302-56-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,0 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72302-56:
(7*7)+(6*2)+(5*3)+(4*0)+(3*2)+(2*5)+(1*6)=98
98 % 10 = 8
So 72302-56-8 is a valid CAS Registry Number.
