Check Digit Verification of cas no

The CAS Registry Mumber 919288-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,9,2,8 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 919288-53:
(8*9)+(7*1)+(6*9)+(5*2)+(4*8)+(3*8)+(2*5)+(1*3)=212
212 % 10 = 2
So 919288-53-2 is a valid CAS Registry Number.

An interesting issue of Diels-Alder selectivity discovered en route to 11-O-debenzoyltashironin

Cook, Silas P.,Danishefsky, Samuel J.

, p. 5693 - 5695 (2007/10/03)

(Diagram presented) The hypervalent iodine-mediated oxidative dearomatization/Diels-Alder cascade was examined in the context of the natural product 11-O-debenzoyltashironin. Interestingly, the regioselectivity of the Diels-Alder reaction can be completely switched by changing the dienophile. Trapping of allyl alcohols during the oxidative dearomatization gives rise to the five-membered acetal, while trapping of allenyl alcohols results in the six-membered acetal.
