154232-83-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154232-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,2,3 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 154232-83:
(8*1)+(7*5)+(6*4)+(5*2)+(4*3)+(3*2)+(2*8)+(1*3)=114
114 % 10 = 4
So 154232-83-4 is a valid CAS Registry Number.

Molecular diversity of tonghaosu: Synthesis of lactam-containing tonghaosu analogs
Yin, Biao-Lin,Yang, Zheng-Min,Hu, Tai-Shan,Wu, Yu-Lin
, p. 1995 - 2000 (2007/10/03)
A new type of tonghaosu analogs containing spiroketal and lactam functionality was synthesized from methyl 2-furoate and amino alcohols. The stereoselective control of spiroketal chirality was also explored.
