The CAS Registry Mumber 87234-40-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,3 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87234-40:
(7*8)+(6*7)+(5*2)+(4*3)+(3*4)+(2*4)+(1*0)=140
140 % 10 = 0
So 87234-40-0 is a valid CAS Registry Number.

Reaction of Ethyl Chloroformate with Dianions of 1,2-Diketones

Joshi, S. C.

, p. 502 - 503 (2007/10/02)

The title reaction using benzil, p-toluil and 9,10-phenanthraquinone as diketones leads to the formation of substituted vic-di(ethyl carbonates).However, anisil yields anisoin monoethyl carbonate and anisilic acid.The products have been characterised on the basis of elemental analyses and spectral (UV, IR and PMR) data.
