658051-11-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 658051-11-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,8,0,5 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 658051-11:
(8*6)+(7*5)+(6*8)+(5*0)+(4*5)+(3*1)+(2*1)+(1*1)=157
157 % 10 = 7
So 658051-11-7 is a valid CAS Registry Number.

A Synthesis of the Diazonamide Heteroaromatic Biaryl Macrocycle/Hemiaminal Core
Zajac, Matthew A.,Vedejs, Edwin
, p. 237 - 240 (2007/10/03)
(Matrix presented) Stille coupling of an arylstannane aminal 19 with the palladium complex 23 leads to atropisomeric esters 28 and 29. Conversion to macrocycle 30 is demonstrated, a potential precursor of natural and unnatural diazonamides.
