786668-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 786668-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,6,6,6 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 786668-31:
(8*7)+(7*8)+(6*6)+(5*6)+(4*6)+(3*8)+(2*3)+(1*1)=233
233 % 10 = 3
So 786668-31-3 is a valid CAS Registry Number.

Access to both anomers of pectenotoxin spiroketals by kinetic spiroketalization
Pihko, Petri M.,Aho, Jatta E.
, p. 3849 - 3852 (2007/10/03)
A concise synthesis of both AB ring spiroisomers of the pectenotoxins is described. The nonanomeric AB spiroketal ring system of the pectenotoxins-1, -2, -3, and -6 is formed under very mild, kinetic spiroketalization conditions, along with the anomeric i
