Check Digit Verification of cas no

The CAS Registry Mumber 628292-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,8,2,9 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 628292-92:
(8*6)+(7*2)+(6*8)+(5*2)+(4*9)+(3*2)+(2*9)+(1*2)=182
182 % 10 = 2
So 628292-92-2 is a valid CAS Registry Number.

Simple access to a 2,4-diphosphabicyclobutane

White, Marcus,Ricard, Louis,Mathey, Francois

, p. 4825 - 4828 (2008/10/09)

A 2-(phosphirenyl)ethylphosphinidene [W(CO)5]2 complex undergoes an original phosphinidene + phosphirene self-condensation to yield the tricyclic compound 5 with an unusual 2,4-diphosphabicyclobutane "butterfly" structure. The product has been characterized by X-ray crystal structure analysis and its formation studied from a theoretical standpoint at the B3LYP/6-311+G(d,p) level.
