299410-01-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 299410-01-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,4,1 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 299410-01:
(8*2)+(7*9)+(6*9)+(5*4)+(4*1)+(3*0)+(2*0)+(1*1)=158
158 % 10 = 8
So 299410-01-8 is a valid CAS Registry Number.

Addition of OH and alcohols or amines to -C≡N and -CH=CH2 groups of CH2=CHCN coordinated to Cp*Ir(η3-CH2CHCHPh)

Chin, Chong Shik,Chong, Daesung,Lee, Soojin,Park, Young Ja

, p. 4043 - 4050 (2008/10/08)

Hydroxide ion and alcohols or amines are added regioselectively to the -C≡N and -CH= CH2 groups of CH2=CHCN in [Cp*Ir(η3-CH2CHCHPh)(NCCH=CH2)] + (1a). The unsaturated amido complex Cp*Ir(η3-CH2CHCHPh)(NHCOCH=CH2) (2a), alkoxo amido complexes Cp*Ir-(η3-CH2CHCHPh)(NHCOCH2CH 2OR) (4, R = Me (a), Et (b)), amino amido complexes Cp*Ir-(η3-CH2CHCHPh)(NHCOCH2CH 2NR2) (6, R2 = Me2 (a), (Me)(H) (b)), and an amino iminoether complex [Cp*Ir(η3-CH2CHCHPh)(NH=C(OMe)CH 2CH2NMe2)]+ (8) have been prepared from the reactions of 1a with OH-, OR-/ROH (R = Me, Et), OH-/HNR2 (R2 = Me2, (Me)-(H)), and MeOH/NHMe2, respectively. Reactions of 2, 4, 6, and 8 with aqueous HCl yield Cp*IrCl(η3-CH2CHCHPh) and quantitative amounts of H2NCOCH=CH2 H2NCOCH2CH2-OR, H2NCOCH2CH2NR2, and MeOCOCH2CH2NMe2, respectively. Crystal structures of 1a and 4a have been determined by X-ray diffraction data analysis.
