Check Digit Verification of cas no

The CAS Registry Mumber 79433-14-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,3 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 79433-14:
(7*7)+(6*9)+(5*4)+(4*3)+(3*3)+(2*1)+(1*4)=150
150 % 10 = 0
So 79433-14-0 is a valid CAS Registry Number.

Intramolecular Cyclization of Nerol and the Related Attack of (Z)-Allylic Alcohol Moiety on the Terminal Olefin Linkage as Induced by TiCl4-PhNHMe Complex. Synthesis of Nezukone

Itoh, Akira,Saito, Tadashi,Oshima, Koichiro,Nozaki, Hitosi

, p. 1456 - 1459 (1981)

Nerol was cyclized to terpinyl chloride or bromide in the presence of TiX4-PhNHMe (1:1) complex (I, X=Cl, Br) in dichloromethane at -23 deg C, geraniol being converted into geranyl halide by simple halogenation.Terminally modified derivatives YCH2C(Me)=CHCH2CH2CMe=CHCH2OH (Y=SiMe3, SnBu3) of (2Z,6E) configuration were cyclized by treatment with I to afford limonene in high yields and 100percent selectivity.Cyclization of (2Z) isomers of CH2=CR-CH2CH2CMe=CHCH2OH (R=H, Me, Cl) produced seven-membered carbocyclic products in fair yields.The novel procedure has been utilized in the synthesis of nezukone from (2E)-3-isopropyl-2,6-heptadien-1-ol involving five steps.
