216449-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 216449-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,4,4 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 216449-87:
(8*2)+(7*1)+(6*6)+(5*4)+(4*4)+(3*9)+(2*8)+(1*7)=145
145 % 10 = 5
So 216449-87-5 is a valid CAS Registry Number.

An enantiocontrolled synthesis of a key intermediate to (+)-lactacystin
Kang, Sung Ho,Jun, Hyuk-Sang
, p. 1929 - 1930 (2007/10/03)
An asymmetric synthesis of a key intermediate 16 to (+)-lactacystin 1 has been established starting from epoxide 2 via intramolecular mercurioamidation of allylic trichloroacetimidate 4 and concomitant addition-reduction of ester 13 by Pr(i) MgBr, in whic
