Check Digit Verification of cas no
The CAS Registry Mumber 68661-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,6,6 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 68661-23:
(7*6)+(6*8)+(5*6)+(4*6)+(3*1)+(2*2)+(1*3)=154
154 % 10 = 4
So 68661-23-4 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.
