Check Digit Verification of cas no

The CAS Registry Mumber 177913-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,9,1 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 177913-75:
(8*1)+(7*7)+(6*7)+(5*9)+(4*1)+(3*3)+(2*7)+(1*5)=176
176 % 10 = 6
So 177913-75-6 is a valid CAS Registry Number.

Cycloaddition reactions of carbohydrate derivatives. Part 8: Intramolecular cycloaddition of nitrilimines derived from sugars

Agocs, Attila,Gunda, Tamas E.,Batta, Gyula,Kovacs-Kulyassa, Arpad,Herczegh, Pal

, p. 469 - 476 (2007/10/03)

Nitrilimines containing a carbon-carbon double bond were prepared in several steps from 2,3,4-tri-O-benzyl-D-xylose, D-ribose and L-arabinose derivatives and their intramolecular 1,3-dipolar cycloaddition reactions were studied. The results were examined

A new synthesis of carbapentofuranoses from carbohydrates

Desire, Jerome,Prandi, Jacques

, p. 6189 - 6192 (2007/10/03)

Carbafuranosides were synthesized in one step from various O-protected 1,2,6-trideoxy-6-iodo-hex-1-enitols by cobalt catalyzed 5-exo radical-cyclization under molecular oxygen. Yields were fair to good with interesting selectivities.
