Check Digit Verification of cas no
The CAS Registry Mumber 841235-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,1,2,3 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 841235-49:
(8*8)+(7*4)+(6*1)+(5*2)+(4*3)+(3*5)+(2*4)+(1*9)=152
152 % 10 = 2
So 841235-49-2 is a valid CAS Registry Number.

New approaches to bicylic vinyl heterocycles from propargylic acetals
Le Strat, Frederic,Harrowven, David C.,Maddaluno, Jacques
, p. 489 - 498 (2007/10/03)
(Chemical Equation Presented) The paper describes further studies on the intramolecular carbolithiation of propargylic acetals with aryllithiums leading to 2-vinylbenzofurans and 3-vinylfuropyridines. Attempts to extend the cascade to [4.4.0] binuclear he
