243657-75-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 243657-75-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,6,5 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 243657-75:
(8*2)+(7*4)+(6*3)+(5*6)+(4*5)+(3*7)+(2*7)+(1*5)=152
152 % 10 = 2
So 243657-75-2 is a valid CAS Registry Number.

Gazard, M. M.,Ogorodniichuk, A. S.,Shilin, V. V.,Vasil'ev, S. A.,Turov, A. V.,Khilya, V. P.

, p. 435 - 441 (2007/10/03)

A series of 5,7-dihydroxy-3-phenoxychromones and their 2-methyl analogs has been obtained by the heterocyclization of α-aryloxy-2,4,6-trihydroxyacetophenones. Their acylation, alkylation, and aminoacylation reactions have been studied.
