104114-70-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104114-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,1,1 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 104114-70:
(8*1)+(7*0)+(6*4)+(5*1)+(4*1)+(3*4)+(2*7)+(1*0)=67
67 % 10 = 7
So 104114-70-7 is a valid CAS Registry Number.

Enantioselective Ring Cleavage of meso-Epoxides with B-Halodiisopinocampheylboranes
Joshi, N. N.,Srebnik, M.,Brown, Herbert C.
, p. 6246 - 6248 (2007/10/02)
Asymmetric synthesis starting from meso compounds is an increasingly important method for the preparation of optically active compound.We now report the synthesis of optically active 1,2-halohydrins using B-halodiisopinocampheylboranes, Ipc2BX (1a-c).
