915105-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 915105-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,5,1,0 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 915105-89:
(8*9)+(7*1)+(6*5)+(5*1)+(4*0)+(3*5)+(2*8)+(1*9)=154
154 % 10 = 4
So 915105-89-4 is a valid CAS Registry Number.

Racemization in prins cyclization reactions
Jasti, Ramesh,Rychnovsky, Scott D.
, p. 13640 - 13648 (2007/10/03)
Isotopic labeling experiments were performed to elucidate a new mechanism for racemization in Prins cyclization reactions. The loss in optical activity for these reactions was shown to occur by 2-oxonia-Cope rearrangements by way of a (2)-oxocarbenium ion
