1204403-08-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1204403-08-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,4,0 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1204403-08:
(9*1)+(8*2)+(7*0)+(6*4)+(5*4)+(4*0)+(3*3)+(2*0)+(1*8)=86
86 % 10 = 6
So 1204403-08-6 is a valid CAS Registry Number.

Inherently chiral biscalix[4]arenes: Design and syntheses
Luo, Jun,Shen, Li-Ching,Chung, Wen-Sheng
experimental part, p. 464 - 467 (2010/03/30)
(Chemical Equation Presented) Inherently chiral biscalix[4]arenes have been designed and synthesized by covalently assembling two calix[4]arene building blocks in a 1,3-position linking with 1,2-position pattern at the lower rims via two triethylene glycol bridges.
