Check Digit Verification of cas no

The CAS Registry Mumber 109248-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,4 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109248-43:
(8*1)+(7*0)+(6*9)+(5*2)+(4*4)+(3*8)+(2*4)+(1*3)=123
123 % 10 = 3
So 109248-43-3 is a valid CAS Registry Number.

Efficient one-pot synthesis of hydroxyflavanones by cyclization and O-demethylation of methoxychalcones

Liu, Tao,Ying, Huazhou,Lin, Guan,Hu, Yongzhou

, p. 1815 - 1821 (2008/12/20)

An efficient one-pot method for the synthesis of hydroxyflavanones is described. Methoxychalcones are treated with 36% HBr to afford cyclization and regioselective O-demethylation products (2a-i) while cyclization and complete O-demethylation products (3a
