Check Digit Verification of cas no

The CAS Registry Mumber 55683-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,8 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 55683-21:
(7*5)+(6*5)+(5*6)+(4*8)+(3*3)+(2*2)+(1*1)=141
141 % 10 = 1
So 55683-21-1 is a valid CAS Registry Number.

Cyclopentadiene with two coordinating sites: 1,5-bis(diphenylphosphino) -2,3,4-trimethylcyclopenta-1,3-diene

Broussier, Roland,Ninoreille, Serge,Legrand, Corinne,Gautheron, Bernard

, p. 55 - 60 (2007/10/03)

The possibility of obtaining the new bidentate 1,2-diphenylphosphinocyclopentadienyl ligand has been studied. 1,5-bis(diphenylphosphino)-2,3,4-trimethylcyclopenta-1,3-diene can be formed from butanone and chlorodiphenylphosphine in eight steps. The results of chemical and spectroscopic studies reveal that a 1,5-sigmatropic migration of the diphenylphosphino group takes place: the 1,2-diphenylphosphino-substituted species are converted into 1,3 species.
