808144-26-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 808144-26-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,8,1,4 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 808144-26:
(8*8)+(7*0)+(6*8)+(5*1)+(4*4)+(3*4)+(2*2)+(1*6)=155
155 % 10 = 5
So 808144-26-5 is a valid CAS Registry Number.

Synthesis of a cryptand with tetrahedral connectivity using multiple ring-closing olefin metathesis
Fang, Shiyue,Bergstrom, Donald E.
, p. 8501 - 8504 (2007/10/03)
By connecting six terminal olefins sequentially in one molecule under metathesis conditions, three macrocycles were formed efficiently in one pot yielding a novel cryptand with tetrahedral connectivity.
