Check Digit Verification of cas no

The CAS Registry Mumber 17202-89-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,0 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17202-89:
(7*1)+(6*7)+(5*2)+(4*0)+(3*2)+(2*8)+(1*9)=90
90 % 10 = 0
So 17202-89-0 is a valid CAS Registry Number.

Selective Reactions of Azide-Substituted α-Diazo Amides with Olefins and Alcohols Using Rhodium(II) Catalysts

Jeganathan, Alwarsamy,Richardson, Steward K.,Mani, Rajarathnam S.,Haley, Boyd E.,Watt, David S.

, p. 5362 - 5367 (2007/10/02)

The synthesis and addition of azide-substituted α-diazo amides such as N-(4-azidophenyl)-α-diazoacetamide and N-(4-azido-2-hydroxyphenyl)-α-diazoacetamide to olefins and alcohols using either rhodium(II) acetate or preferably rhodium(II) pivalate provided cyclopropanecarboxamides and α-alkoxy amides, respectively, without disrupting the azide functionality.These azide-bearing α-diazo amides are potentially useful in the preparation of photoaffinity cross-linking reagents for studying the mechanism of action of natural products.
