Check Digit Verification of cas no

The CAS Registry Mumber 1618682-17-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,8,6,8 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1618682-17:
(9*1)+(8*6)+(7*1)+(6*8)+(5*6)+(4*8)+(3*2)+(2*1)+(1*7)=189
189 % 10 = 9
So 1618682-17-9 is a valid CAS Registry Number.

3-Halotetrahydropyran-4-one derivatives from homopropargyl acetal

Aaseng, Jon Erik,Iqbal, Naseem,Tungen, Jorn Eivind,Sperger, Christian A.,Fiksdahl, Anne

, p. 2458 - 2467 (2014)

GRAPHICAL ABSTRACT A gold(I)-catalyzed regioselective method for the preparation of 3-bromo/iodo-tetrahydropyran-4-one derivatives from homopropargyl acetal is reported. A one-pot procedure based on a gold(I)-catalyzed Petasis-Ferrier rearrangement/cyclization and subsequent electrophilic halogenation was developed. Corresponding hemiacetals were not suitable substrates for the formation of the 3-halo-pyran derivatives. The present transformation is a useful method to readily afford highly substituted 3-halo-tetrahydropyran-4-ones, which are suitable substrates in a variety of reactions in further synthesis.
