Check Digit Verification of cas no

The CAS Registry Mumber 1353021-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,0,2 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1353021-40:
(9*1)+(8*3)+(7*5)+(6*3)+(5*0)+(4*2)+(3*1)+(2*4)+(1*0)=105
105 % 10 = 5
So 1353021-40-5 is a valid CAS Registry Number.

Palladium-catalyzed asymmetric synthesis of 2-alkynyl oxacycles

Daniels, David S. B.,Thompson, Amber L.,Anderson, Edward A.

, p. 11506 - 11510 (2012/01/11)

Oxyacetylene: Unusual palladium-catalyzed cyclizations of cyclic and acyclic propargylic carbonates give 2-alkynyl oxacycles. The reactions proceed with very high stereoselectivity for both syn- and anti-disubstituted furans and pyrans, and with exceptional regioselectivity. In addition, two-directional cyclizations of bis-propargylic carbonate substrates yield bifurans with complete stereocontrol for all diastereomers.
