(+/-)-2-oxo-bornane-10-sulfonic acid methyl ester is used as a chiral resolving agent and catalyst in the production of functional materials due to its ability to facilitate asymmetric synthesis and separation of enantiomers.
Check Digit Verification of cas no
The CAS Registry Mumber 83603-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,0 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83603-04:
(7*8)+(6*3)+(5*6)+(4*0)+(3*3)+(2*0)+(1*4)=117
117 % 10 = 7
So 83603-04-7 is a valid CAS Registry Number.
