"O2, O3, O4, O5-tetraacetyl-D-glucaric acid dimethyl ester" is a complex organic compound derived from D-glucaric acid, a sugar acid. O2,O3,O4,O5-tetraacetyl-D-glucaric acid dimethyl ester is characterized by the presence of four acetyl groups (-COCH3), which are attached to the hydroxyl groups (-OH) at the 2nd, 3rd, 4th, and 5th carbon positions of the glucaric acid backbone. The term "dimethyl ester" indicates that the carboxylic acid groups at both ends of the molecule have been esterified with methanol (CH3OH), resulting in two methyl ester groups (-COOCH3). This chemical modification can influence the compound's reactivity, solubility, and other physical properties, making it useful in various chemical and pharmaceutical applications. The specific arrangement of acetyl and methyl ester groups gives O2,O3,O4,O5-tetraacetyl-D-glucaric acid dimethyl ester unique chemical properties that can be exploited in research and development.
The CAS Registry Mumber 3868-18-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,6 and 8 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3868-18: (6*3)+(5*8)+(4*6)+(3*8)+(2*1)+(1*8)=116 116 % 10 = 6 So 3868-18-6 is a valid CAS Registry Number.
