Check Digit Verification of cas no

The CAS Registry Mumber 138055-96-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,5 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138055-96:
(8*1)+(7*3)+(6*8)+(5*0)+(4*5)+(3*5)+(2*9)+(1*6)=136
136 % 10 = 6
So 138055-96-6 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.
