105601-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105601-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,6,0 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 105601-98:
(8*1)+(7*0)+(6*5)+(5*6)+(4*0)+(3*1)+(2*9)+(1*8)=97
97 % 10 = 7
So 105601-98-7 is a valid CAS Registry Number.

Reaction of Aldonitrones with Copper Acetylide : Synthesis of Some Novel β-Lactams
Dutta, D. K.,Boruah, R. C.,Sandhu, J. S.
, p. 350 - 353 (2007/10/02)
Nitrones (7a-e) react with copper acetylide (6) to afford cis- and trans-β-lactams (8 and 9) in good yields.The cis- and trans-isomers have been isolated, respectively as the major and minor products and are characterized through spectral data (IR, mass a
