1438408-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1438408-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,4,0 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1438408-40:
(9*1)+(8*4)+(7*3)+(6*8)+(5*4)+(4*0)+(3*8)+(2*4)+(1*0)=162
162 % 10 = 2
So 1438408-40-2 is a valid CAS Registry Number.

, p. 5231 - 5233 (2013/06/27)
(-)-Kaitocephalin has been synthesized. With the C9 stereocenter from Garner's aldehyde, the C4 quaternary carbon was installed by the desymmetrization of the Cbz-protected serinol. The remaining stereogenic centers were generated through mercuriocyclizat
