Check Digit Verification of cas no

The CAS Registry Mumber 102235-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,2,3 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 102235-57:
(8*1)+(7*0)+(6*2)+(5*2)+(4*3)+(3*5)+(2*5)+(1*7)=74
74 % 10 = 4
So 102235-57-4 is a valid CAS Registry Number.

A general route to 4-C-branched sugars. Synthesis of methyl α-caryophylloside

Prandi, Jacques

, p. 241 - 247 (2001)

The total synthesis of methyl 3,6-dideoxy-4-C-(D-altro-1,3,4,5 tetrahydroxyhexyl)-α-D-xylo-hexopyranoside, the methyl glycoside of the recently isolated 4-C-branched sugar caryophyllose, has been completed in a stereoselective and convergent manner. The synthesis of this dodecose relies on the diiodosamarium mediated coupling of two six-carbon fragments: a cyclic ketone and an acid chloride.

De novo Synthesis of Carbohydrates and Related Natural Products, 22. - Synthesis of D-Digitoxose from meso-Divinylglycol

Kuefner, Ulrike,Schmidt, Richard R.

, p. 1600 - 1609 (2007/10/02)

Selective monobenzylation of meso- and rac-divinylglycol (2-m and 2-d,l) affords racemates (+/-)-8 and (+/-)-10, respectively; they are transferred with the help of the Sharpless method under kinetic racemate resolution diastereoselectively into the enant
