630402-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 630402-99-2 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 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 630402-99:
(8*6)+(7*3)+(6*0)+(5*4)+(4*0)+(3*2)+(2*9)+(1*9)=122
122 % 10 = 2
So 630402-99-2 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.
