Check Digit Verification of cas no

The CAS Registry Mumber 102697-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,6,9 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 102697-22:
(8*1)+(7*0)+(6*2)+(5*6)+(4*9)+(3*7)+(2*2)+(1*2)=113
113 % 10 = 3
So 102697-22-3 is a valid CAS Registry Number.

Synthesis and Spectral Data of Ethyl 3-Aryl-4,5-diphenyl-5-oxopentanoates

Al-Arab, Mohammad M.,Issa, Ali M.

, p. 376 - 377 (2007/10/02)

The Michael reaction of substituted ethyl cinnamates with α-phenylacetophenone in the presence of sodium ethoxide at room temperature gave a mixture of erythro- and threo-ethyl 3-aryl-4,5-diphenyl-5-oxopentanoates.The reaction products were identified by their elemental analysis, nuclear magnetic resonance, infrared, and mass spectral data.
