77471-71-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77471-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,7 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77471-71:
(7*7)+(6*7)+(5*4)+(4*7)+(3*1)+(2*7)+(1*1)=157
157 % 10 = 7
So 77471-71-7 is a valid CAS Registry Number.

THE PHOTOELECTRON SPECTRA OF 4-METHYLENE THIACYCLOHEXANE DERIVATIVES THROUGH-BOND INTERACTION

Sarneel, R.,Worell, C. W.,Pasman, P.,Verhoeven, J. W.,Mes, G. F.

, p. 3241 - 3248 (2007/10/02)

The photoelectron spectra of 4-methylene thiacyclohexane, 4-difluoromethylene thiacyclohexane and trans-2-methylene-6-thiaperhydronaphthalene are described and compared with thiacyclohexane, difluoromethylene-cyclohexane and cis-2-methylene-6-thiaperhydronaphthalene.A through bond interaction between the sulphur lone pair and the vinyl-?-system is observed.The results are discussed in relation with the sigma-coupled transition observed in the electronic absorption spectra of the dicyano methylene derivatives by P.Pasman.
