182352-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 182352-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,3,5 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 182352-44:
(8*1)+(7*8)+(6*2)+(5*3)+(4*5)+(3*2)+(2*4)+(1*4)=129
129 % 10 = 9
So 182352-44-9 is a valid CAS Registry Number.

A facile solid phase synthesis of tetramic acid
Liu, Zhanxiang,Ruan, Xiuxiu,Huang, Xian
, p. 2505 - 2507 (2007/10/03)
The condensation of N-acylated amino acids with polymer-supported cyclic malonic acid ester was carried out in the presence of DCC/DMAP. The cyclisation of the intermediate resin, by heating in an organic solvent, gave the N-protected tetramic acid derivatives in good yields and high purity.
