Check Digit Verification of cas no

The CAS Registry Mumber 34693-27-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,9 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34693-27:
(7*3)+(6*4)+(5*6)+(4*9)+(3*3)+(2*2)+(1*7)=131
131 % 10 = 1
So 34693-27-1 is a valid CAS Registry Number.

Beneficial effect of internal hydrogen bonding interactions on the β-fragmentation of primary alkoxyl radicals. Two-step conversion of D-xylo- and D-ribofuranoses into L-threose and D-erythrose, respectively

Hernandez-Garcia, Luis,Quintero, Leticia,Sanchez, Mario,Sartillo-Piscil, Fernando

, p. 8196 - 8201 (2007)

(Chemical Equation Presented) Primary alkoxyl free radicals were generated from their readily synthesized N-phthalimido derivatives under reductive conditions. Primary alkoxyl radicals derived from their corresponding xylo- and ribofuranose derivatives underwent, exclusively, an unusual β-fragmentation affording L-threose and D-erythrose derivatives, respectively. This occurs because the alkoxyl radical is capable of achieving an internal hydrogen-bonding interaction leading to a stable six-membered ring intramolecular hydrogen-bonded structure. When the hydroxyl group is protected, the β-fragmentation pathway is prevented and the hydrogen atom transfer (HAT) pathway occurs. Computational studies provided strong support for the experimental observations.
