Check Digit Verification of cas no
The CAS Registry Mumber 2302-97-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,0 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2302-97:
(6*2)+(5*3)+(4*0)+(3*2)+(2*9)+(1*7)=58
58 % 10 = 8
So 2302-97-8 is a valid CAS Registry Number.
