Check Digit Verification of cas no

The CAS Registry Mumber 105787-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,7,8 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 105787-72:
(8*1)+(7*0)+(6*5)+(5*7)+(4*8)+(3*7)+(2*7)+(1*2)=142
142 % 10 = 2
So 105787-72-2 is a valid CAS Registry Number.

Low Coordinated Phosphorus Compounds, 55. - Cope Rearrangement of 1,3-Diphospha-1,5-hexadienes

Appel, Rolf,Kochta, Joachim,Knoch, Falk

, p. 131 - 134 (2007/10/02)

Chlorophosphane 1 reacts with substituted allyl-Grignard reagents 2a, b to yield the 1,3-diphospha-1,5-hexadienes 3a, 4b. 31P-NMR temperature run of 3a shows dynamic processes, which can be explained by inversion of the trivalent P-atom.Above 40 deg C 3a undergoes a -phospha-carbon Cope rearrangement to give the thermodynamically stable product 4a.The structures of 3a and 4a are confirmed by X-ray structure analysis.
