132115-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132115-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,1,1 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 132115-04:
(8*1)+(7*3)+(6*2)+(5*1)+(4*1)+(3*5)+(2*0)+(1*4)=69
69 % 10 = 9
So 132115-04-9 is a valid CAS Registry Number.

Allyl cation stereochemistry in the intramolecular 4+3 cycloaddition reaction
Harmata,Gamlath,Barnes
, p. 5981 - 5984 (2007/10/02)
Initial allyl cation geometry appears to be irrelevant with respect to the stereochemistry of cycloadducts in the intramolecular 4+3 cycloaddition of alkoxyallylic cations derived from alkoxyallylic sulfones.
