Check Digit Verification of cas no

The CAS Registry Mumber 3399-27-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,9 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3399-27:
(6*3)+(5*3)+(4*9)+(3*9)+(2*2)+(1*7)=107
107 % 10 = 7
So 3399-27-7 is a valid CAS Registry Number.

Acid-Induced Rearrangement of Triterpenoid Hydrocarbons Belonging to the Hopane and Migrated Hopane Series

Ageta, Hiroyuki,Shiojima, Kenji,Arai, Yoko

, p. 2705 - 2716 (2007/10/02)

The acid-catalyzed rearrangement of triterpenoid monoenes belonging to the hopane and migrated hopane series with sulfuric acid and boron trifluoride etherate was investigated.By selecting the reaction conditions, a variety of the monoenes of these series, including three new compounds, 9βH-fern-7-ene (3c), 8βH-fern-9(11)-ene (4b), and adian-5(10)-ene (5b), were obtained.For comparison, oleanenes and migrated oleanenes were also subjected to the same reaction.Keywords--acid-induced rearrangement; triterpenoid hydrocarbon; hopane, migrated hopane; 9βH-fern-7-ene; 8βH-fern-9(11)-ene; adian-5(10)-ene; sulfuric acid; boron trifluoride
