Check Digit Verification of cas no

The CAS Registry Mumber 160060-61-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,0,6 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 160060-61:
(8*1)+(7*6)+(6*0)+(5*0)+(4*6)+(3*0)+(2*6)+(1*1)=87
87 % 10 = 7
So 160060-61-7 is a valid CAS Registry Number.

Preparation of -, -, and -Bicyclic Guanidines from C,C'-Bis(iminophosphoranes)

Molina, Pedro,Obon, Rosario,Conesa, Carlota,Arques, Antonio,Desamparados Velasco, M. de los,et al.

, p. 1641 - 1652 (2007/10/02)

A one-pot synthesis of -, -, and -rigid bicyclic guanidines (6, 8, 19, 21, 23) based on a bis(iminophosphorane)-mediated annulation strategy is reported.The crystal and molecular structure of the parent -bicyclic guanidine 8 has been established by X-ray diffraction.The crystallographically independent molecule forms dimers through a centre of symmetry by N-H***N hydrogen bonds.The molecule, and therefore the dimer, is statistically disordered in a 65/35 ratio.A statistical study of N-H***N hydrogen bonds of this kind of dimers has been carried out by using the Cambridge Structural Database. - Key Words: Bis(iminophosphoranes) / Guanidines, bicyclic / Aza Wittig reaction
