(2R,3R)-2-Dimethoxymethyl-3-((2S,4S,5R)-3,4-dimethyl-5-phenyl-oxazolidin-2-yl)-cyclopropane-1,1-dicarboxylic acid dimethyl ester is a complex organic compound with a molecular formula of C20H27NO6. It features a cyclopropane ring with two chiral centers at the 2nd and 3rd positions, which are occupied by a dimethoxymethyl group and an oxazolidinyl group, respectively. The oxazolidinyl group itself has three chiral centers, with the 2nd position being occupied by a hydrogen atom, the 4th position by a methyl group, and the 5th position by a phenyl group. The compound also contains two ester groups, which are derived from dimethyl ester. This chemical is known for its potential applications in pharmaceuticals and as a chiral building block in the synthesis of various biologically active compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 82263-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,6 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82263-52:
(7*8)+(6*2)+(5*2)+(4*6)+(3*3)+(2*5)+(1*2)=123
123 % 10 = 3
So 82263-52-3 is a valid CAS Registry Number.
