Check Digit Verification of cas no

The CAS Registry Mumber 247227-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,2,2 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 247227-98:
(8*2)+(7*4)+(6*7)+(5*2)+(4*2)+(3*7)+(2*9)+(1*8)=151
151 % 10 = 1
So 247227-98-1 is a valid CAS Registry Number.

Short and Divergent Total Synthesis of (+)-Machaeriol B, (+)-Machaeriol D, (+)-Δ8-THC, and Analogues

Klotter, Felix,Studer, Armido

supporting information, p. 8547 - 8550 (2015/11/27)

Short and highly efficient stereoselective syntheses provide machaeriols and cannabinoids in a divergent approach starting from a common precursor, commercially available (S)-perillic acid. Key features of the novel strategy are a stereospecific palladium-catalyzed decarboxylative arylation and a one-pot sequence comprising a stereoselective hydroboration followed by oxidation or reduction of the corresponding intermediary boranes. The divergent approach is convincingly demonstrated by the five-step syntheses of (+)-machaeriol B, (+)-machaeriol D, and related analogues, and the four-step synthesis of (+)-Δ8-THC and an analogue.
