Check Digit Verification of cas no

The CAS Registry Mumber 23040-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,4 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 23040-05:
(7*2)+(6*3)+(5*0)+(4*4)+(3*0)+(2*0)+(1*5)=53
53 % 10 = 3
So 23040-05-3 is a valid CAS Registry Number.

PHASE-TRANSFER ACYLATION OF PHOSPHORUS-CONTAINING CH ACIDS. II. ACYLATION OF PHOSPHINOYLACETONITRILES

Odinets, I. L.,Artyushin, O. I.,Kalyanova, R. M.,Antipin, M. Yu.,Lysenko, K. A.,et al.

, p. 1738 - 1744 (2007/10/03)

Acylation of phosphinoylacetonitriles under conditions of phase-transfer catalysis results in formation of C-acyl derivatives in high yields.According to NMR spectra, the latter have enol structure (Z isomers).Effects of substituents on the phosphorus atom, acylating agents, type of heterophase system, and reaction conditions on the yield of the acylation products were studied. α-Acetyl-α-diphenylphosphinoylacetonitrile in the enol form was studied by x-ray diffraction.
