516526-99-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 516526-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,6,5,2 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 516526-99:
(8*5)+(7*1)+(6*6)+(5*5)+(4*2)+(3*6)+(2*9)+(1*9)=161
161 % 10 = 1
So 516526-99-1 is a valid CAS Registry Number.

The electronic effects of bulky aryl substituents on low coordinated phosphorus atoms in diphosphenes and phosphaalkenes by functionalization at the para position

Kawasaki, Subaru,Nakamura, Akitake,Toyota, Kozo,Yoshifuji, Masaaki

, p. 1110 - 1120 (2005)

The electronic effects of bulky aryl substituents on low coordinated phosphorus atom(s) in diphosphenes and phosphaalkenes have been examined by means of functionalization at the para position of the substituents. Bulky bromobenzenes bearing an electron-d

Development of a new sterically protecting auxiliary of the metacyclophane type and application to unsymmetrical diphosphenes, 1,3-diphosphaallene and 1,4-diphosphabutatriene

Toyota, Kozo,Nakamura, Akitake,Yoshifuji, Masaaki

, p. 3012 - 3013 (2007/10/03)

A new bulky bromobenzene of the metacyclophane type was converted to an unsymmetrically substituted 1,4-diphos-phabutatriene whose spin-spin coupling constant (3JPP) turned out to be larger, for the first time, than the 2J
