98264-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98264-94-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,6 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98264-94:
(7*9)+(6*8)+(5*2)+(4*6)+(3*4)+(2*9)+(1*4)=179
179 % 10 = 9
So 98264-94-9 is a valid CAS Registry Number.

Shibasaki, Masakatsu,Ishida, Yasuko,Okabe, Nobuko
, p. 2217 - 2220 (2007/10/02)
A stereoselective synthesis of the known synthetic intermediate (13) for (-)-carpetimycin A (1) has been achieved starting from the monocyclic β-lactam (8b) by the novel use of the direct aldol condensation of 8b with acetone via the titanium enolate.
