Check Digit Verification of cas no

The CAS Registry Mumber 1335143-97-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,1,4 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1335143-97:
(9*1)+(8*3)+(7*3)+(6*5)+(5*1)+(4*4)+(3*3)+(2*9)+(1*7)=139
139 % 10 = 9
So 1335143-97-9 is a valid CAS Registry Number.

Merging metathesis and photochemical Csp3-H activation: Access to masked β-formyl hexanolides and their rearrangement to furofuranones

Glenadel, Quentin,Nassar, Youssef,Raffier, Ludovic,Veys, Sebastiaan,Piva, Olivier

, p. 5367 - 5373 (2018)

β-Masked formyl hexanolides were prepared by a three-step sequence including esterification of homoallylic alcohols, ring-closing metathesis and the photochemically induced addition of dioxanyl radical. When treated under oxidative conditions, the adducts underwent cleavage of the ketal group leading after rearrangement to parent furofuranones, structures found in some biological active compounds.

Synthesis and biological evaluation of α,β-unsaturated lactones as potent immunosuppressive agents

Lee, Sun-Mi,Lee, Won-Gil,Kim, Young-Chul,Ko, Hyojin

, p. 5726 - 5729 (2011/10/18)

Compounds having α,β-unsaturated lactones display a variety of biological activities. Many research groups have tested both natural and unnatural α,β-unsaturated lactones for as-yet undiscovered biological properties. We synthesized α,β-unsaturated lacton
