Check Digit Verification of cas no

The CAS Registry Mumber 61034-11-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,0,3 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 61034-11:
(7*6)+(6*1)+(5*0)+(4*3)+(3*4)+(2*1)+(1*1)=75
75 % 10 = 5
So 61034-11-5 is a valid CAS Registry Number.

Mixed Anhydride of Acetic and Formic Acids in the Synthesis of Chromones. 2. Synthesis of 3-Arylchromones

Pivovarenko, V. G.,Khilya, V. P.

, p. 497 - 502 (2007/10/02)

A study was carried out on the reaction of α-substituted 2-hydroxyacetophenones eith the mixed anhydride of acetic and formic acids in the presence of bases of different strength.Chromones containing a conjugated electron-withdrawing substituent at C(3) are formed in close to quantitative yield in the presence of triethylamine.The preparation of chromones containing an unconjugated substituent under these conditions is recommended only for 5-hydroxychromones.
