Check Digit Verification of cas no
The CAS Registry Mumber 137439-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,3 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137439-99:
(8*1)+(7*3)+(6*7)+(5*4)+(4*3)+(3*9)+(2*9)+(1*9)=157
157 % 10 = 7
So 137439-99-7 is a valid CAS Registry Number.

Olivanic Acid Analogues. Part 9. Allylic Oxidative Functionalisation of Substituted Azetidinones: Synthesis of Some 4-Acyloxy-7-oxo-1-azabicyclohept-2-ene-2-carboxylates
Bateson, John H.,Robins, Alison M.,Southgate, Robert
, p. 2399 - 2405 (2007/10/02)
Sharpless oxidation (ButO2H), SeO2) of the protected allyl azetidinone 7 gave the allylic alcohol 8 which was transformed to the 5,6-trans-4α-acetoxyolivanic acid derivative 16.Kharasch-Sosnovsky benzoyloxylation (PhCO3But, CuCl, PhH, heat) of the silylated 7-azabicyclooct-3-enes 17b,c provided inter alia allylic benzoates 18b,c and 21b,c.These were synthetic precursors of the 5,6-cis-olivanic acid analogues 23 and 26, which contain 8- and 4α-benzoyloxy groups, respectively.
