Check Digit Verification of cas no

The CAS Registry Mumber 857088-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,0,8 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 857088-74:
(8*8)+(7*5)+(6*7)+(5*0)+(4*8)+(3*8)+(2*7)+(1*4)=215
215 % 10 = 5
So 857088-74-5 is a valid CAS Registry Number.

Simple and efficient preparation of sterically protected 1,4-diphosphafulvenes

Nakamura, Akitake,Toyota, Kozo,Yoshifuji, Masaaki

, p. 5223 - 5228 (2005)

A new synthetic method for sterically protected 1,4-diphosphafulvenes (2-methylene-2,3-dihydro-1H-[1,3]diphospholes) has been developed starting from (arylethynyl)phosphines and ca. 0.25 molar amount of butyllithium. The catalytic mechanism of the reaction is discussed based on the results of deuterium-labelling experiments.
