852109-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 852109-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,2,1,0 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 852109-68:
(8*8)+(7*5)+(6*2)+(5*1)+(4*0)+(3*9)+(2*6)+(1*8)=163
163 % 10 = 3
So 852109-68-3 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.
