123873-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123873-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,7 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123873-89:
(8*1)+(7*2)+(6*3)+(5*8)+(4*7)+(3*3)+(2*8)+(1*9)=142
142 % 10 = 2
So 123873-89-2 is a valid CAS Registry Number.

SE' ADDITION OF HOMOCHIRAL α-ALKOXYALLYLSTANNANES TO ALDEHYDES
Marshall, James A.,Gung, Wei Yi
, p. 1043 - 1052 (2007/10/02)
Addition of the homochiral (S)- (tri-n-butyl)stannane (5b) to heptanal (1a), (E)-2-heptenal (1b), and 2-heptynal (1c) under BF3 catalysis was examined.In all cases the addition proceeded by anti SE' attack to
