98393-07-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98393-07-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,9 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 98393-07:
(7*9)+(6*8)+(5*3)+(4*9)+(3*3)+(2*0)+(1*7)=178
178 % 10 = 8
So 98393-07-8 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.
