137334-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137334-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,3 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137334-67:
(8*1)+(7*3)+(6*7)+(5*3)+(4*3)+(3*4)+(2*6)+(1*7)=129
129 % 10 = 9
So 137334-67-9 is a valid CAS Registry Number.

Rigidly Hollow Hosts That Encapsulate Small Molecules
Tanner, Martin E.,Knobler, Carolyn B.,Cram, Donald J.
, p. 40 - 46 (2007/10/02)
New chiral host systems 1 and 2 possessing C3 symmetry have been designed and synthesized.Molecular models of 1 and 2 indicate they contain small enforced cavities and three portals complementary to small molecules.The crystal structure of 1*2CH3CN shows
