Calculate Digit Verification of CAS Registry Number 1243985-22:
(9*1)+(8*2)+(7*4)+(6*3)+(5*9)+(4*8)+(3*5)+(2*2)+(1*2)=169
169 % 10 = 9

Grignard additions to cyclic sulfamidate imines: Synthesis of n-substituted quaternary sulfamidate building blocks

Chang, Stanley,Lee, Ernest E.

, p. 2361 - 2366 (2010)

The addition of Grignard reagents to cyclic sulfamidate imines has been developed as a facile method for the synthesis of N-substituted quaternary sulfamidates. By way of ring opening with an appropriate nucleophile, versatile synthons for 1,2-amino alcohols, 1,2-diamines, and β-amino acids are produced. Georg Thieme Verlag Stuttgart · New York.
