Check Digit Verification of cas no

The CAS Registry Mumber 957055-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,0,5 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 957055-41:
(8*9)+(7*5)+(6*7)+(5*0)+(4*5)+(3*5)+(2*4)+(1*1)=193
193 % 10 = 3
So 957055-41-3 is a valid CAS Registry Number.

Indole-derived arynes and their diels - Alder reactivity with furans

Buszek, Keith R.,Luo, Diheng,Kondrashov, Mikhail,Brown, Neil,VanderVelde, David

, p. 4135 - 4137 (2008/02/13)

Arynes derived from any position of the ubiquitous indole nucleus are unknown. We have now provided the first evidence for the formation and trapping of the 4,5-, 5,6-, and 6,7-indolynes. A series of o-dihalo indoles (CI, Br, F) were synthesized and reacted under metal-halogen exchange conditions to give Diels-Alder cycloadducts in high yield with furan. The use of an excess of fert-butyllithium resulted in the rearrangement of the initially formed cycloadduct; however, employing only a slight excess of n-butyllithium cleanly gave cycloadducts with furan.
