Check Digit Verification of cas no

The CAS Registry Mumber 142196-01-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,9 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142196-01:
(8*1)+(7*4)+(6*2)+(5*1)+(4*9)+(3*6)+(2*0)+(1*1)=108
108 % 10 = 8
So 142196-01-8 is a valid CAS Registry Number.

, p. 349 - 353 (2007/10/02)

(Ia) reacted in tetrahydrofuran with cyclopentadiene or cyclohexa-1,4-diene under UV irradiation to give (II), and a 1:2 mixture of and (III), respectively; III was isolated from the photochemical reaction of Ia with 3,3-dimethylbutene in benzene.When using (Ib) (dppe = Ph2PCH2CH2PPh2) instead of Ia in these three reactions, no cyclopentadienyl compound was obtained, but (IV) and (V) were isolated; IV and V are precursors to arene and cyclohexadienylrhenium derivatives containing dppe.
