1291070-03-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1291070-03-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,0,7 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1291070-03:
(9*1)+(8*2)+(7*9)+(6*1)+(5*0)+(4*7)+(3*0)+(2*0)+(1*3)=125
125 % 10 = 5
So 1291070-03-5 is a valid CAS Registry Number.

A convergent route to the CDEF-tetracycle of pectenotoxin-2
Canterbury, Daniel P.,Micalizio, Glenn C.
, p. 2384 - 2387 (2011/06/26)
Chemical equations presented. A convergent synthesis of the CDEF-tetracyclic region of pectenotoxin-2 (PTX-2) is described. The synthetic pathway derives from a head-to-tail union of 2 equiv of linalool to establish a stereodefined DEF-tricyclic aldehyde.
