Check Digit Verification of cas no
The CAS Registry Mumber 207302-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,3,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 207302-98:
(8*2)+(7*0)+(6*7)+(5*3)+(4*0)+(3*2)+(2*9)+(1*8)=105
105 % 10 = 5
So 207302-98-5 is a valid CAS Registry Number.
