176659-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176659-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,6,5 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 176659-55:
(8*1)+(7*7)+(6*6)+(5*6)+(4*5)+(3*9)+(2*5)+(1*5)=185
185 % 10 = 5
So 176659-55-5 is a valid CAS Registry Number.

Synthesis of enantiopure cis-decalins from microbially-derived cis- 1,2-dihydrocatechols
Banwell, Martin G.,Dupuche, Joseph R.
, p. 869 - 870 (2007/10/03)
The microbially-derived cis-1,2-dihydrocatechol 3 is converted, via reaction sequences involving Diels-Alder cycloaddition and anionic oxy-Cope rearrangement steps, into the enantiopure cis-decalins 15 and 26; using simple modifications of this chemistry
