630403-07-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 630403-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,0,4,0 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 630403-07:
(8*6)+(7*3)+(6*0)+(5*4)+(4*0)+(3*3)+(2*0)+(1*7)=105
105 % 10 = 5
So 630403-07-5 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.
