928056-21-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 928056-21-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,0,5 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 928056-21:
(8*9)+(7*2)+(6*8)+(5*0)+(4*5)+(3*6)+(2*2)+(1*1)=177
177 % 10 = 7
So 928056-21-7 is a valid CAS Registry Number.

Strained azetidinium ylides: New reagents for cyclopropanation
Couty, Francois,David, Olivier,Larmanjat, Benedicte,Marrot, Jerome
, p. 1058 - 1061 (2007)
(Chemical Equation Presented) Azetidinium ylides showed a remarkable ability to perform the cyclopropanation of Michael acceptors. Ephedrine-derived azetidinium ylides allowed the formation of substituted cyclopropanes in good yields and at a high level o
