909122-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909122-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,1,2 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 909122-68:
(8*9)+(7*0)+(6*9)+(5*1)+(4*2)+(3*2)+(2*6)+(1*8)=165
165 % 10 = 5
So 909122-68-5 is a valid CAS Registry Number.

Efficient N-heterocyclic carbene-catalyzed O- to C-acyl transfer
Thomson, Jennifer E.,Rix, Kathryn,Smith, Andrew D.
, p. 3785 - 3788 (2006)
An N-heterocyclic carbene promotes the rearrangement of α-amino acid derived O-acyl carbonates to their corresponding C-acylated isomers, generating a C-C bond and a quaternary stereocenter with high efficiency, under mild reaction conditions and with low
