Check Digit Verification of cas no

The CAS Registry Mumber 63569-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,6 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 63569-72:
(7*6)+(6*3)+(5*5)+(4*6)+(3*9)+(2*7)+(1*2)=152
152 % 10 = 2
So 63569-72-2 is a valid CAS Registry Number.

Tricyclic challenges: Synthetic approaches toward dodecahydrocyclopenta[a] indenes

Krebs, Michael,Kalinowski, Matth?us,Frey, Wolfgang,Claasen, Birgit,Baro, Angelika,Schobert, Rainer,Laschat, Sabine

, p. 7373 - 7380 (2013)

Tetrahydrospiro[1,3-dioxolane-2,1′-pentalen]-4′-ones were stereoselectively converted to either (cis,anti,cis)- or (cis,syn)-linear dodecahydrocyclopenta[a]indene isomers employing a 1,4- or 1,2-conjugate addition of organometallic reagents and an intramolecular aldol reaction as the key steps. The relative configuration of the products was determined by X-ray crystal structure analysis and 1D NOE spectroscopy.
