Check Digit Verification of cas no

The CAS Registry Mumber 82246-91-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,4 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82246-91:
(7*8)+(6*2)+(5*2)+(4*4)+(3*6)+(2*9)+(1*1)=131
131 % 10 = 1
So 82246-91-1 is a valid CAS Registry Number.

Directed ortho Metallation Studies on Podocarpic Acid Derivatives: Advantageous Use of a LICKOR Base

Cambie, Richard C.,Higgs, Paul I.,Lee, Kee Chee,Metzler, Michael R.,Rutledge, Peter S.,at al.

, p. 1465 - 1477 (2007/10/02)

Methyl 13-(N,N-diethylcarbamoyl)-12-methoxypodocarpa-8,11,13-trien-19-oate (2), 13-(N,N-diethylcarbamoyl)-12,19-dimethoxypodocarpa-8,11,13-triene (8) and N,N-diethyl-2-methoxy-4,5-dimethylbenzamide (15) were prepared for studies involving lithiation directed ortho to the tertiary amide group, in which the use of a LICKOR base was advantageous.Some dynamic features of the n.m.r. spectra of the amides are discussed.Oxazoline derivatives of both the monocyclic and diterpenoid compounds were synthesized.
