Check Digit Verification of cas no
The CAS Registry Mumber 30987-48-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,9,8 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 30987-48:
(7*3)+(6*0)+(5*9)+(4*8)+(3*7)+(2*4)+(1*8)=135
135 % 10 = 5
So 30987-48-5 is a valid CAS Registry Number.

Catalytic Carbonylative Spirolactonization of Hydroxycyclopropanols
Davis, Dexter C.,Walker, Katherine L.,Hu, Chunhua,Zare, Richard N.,Waymouth, Robert M.,Dai, Mingji
, p. 10693 - 10699 (2016)
A palladium-catalyzed cascade carbonylative spirolactonization of hydroxycyclopropanols has been developed to efficiently synthesize oxaspirolactones common to many complex natural products of important therapeutic value. The mild reaction conditions, high atom economy, broad substrate scope, and scalability of this new method were highlighted in expedient total syntheses of the Turkish tobacco natural products α-levantanolide and α-levantenolide in two and four steps, respectively. The hydroxycyclopropanol substrates are readily available in one step via a Kulinkovich reaction of the corresponding lactones. Mechanistic studies utilizing high-resolution electrospray ionization mass spectrometry (ESI-MS) identified several key intermediates in the catalytic cycle, as well as those related to catalyst decomposition and competitive pathways.
