129076-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129076-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,7 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129076-61:
(8*1)+(7*2)+(6*9)+(5*0)+(4*7)+(3*6)+(2*6)+(1*1)=135
135 % 10 = 5
So 129076-61-5 is a valid CAS Registry Number.

Selective nucleophilic transformations of cyclopentadienone epoxides
Houwen-Claassen, Adrie A. M.,Klunder,Zwanenburg
, p. 2593 - 2610 (2007/10/02)
Acid-catalysed solvolyses of cyclopentadienone epoxides lead to epoxide ring opening and take place regioselectively at C-4. The stereochemical outcome of the epoxide ring opening depends on the substitution pattern and the nature of the substituents. Tra
