104898-02-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104898-02-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,9 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104898-02:
(8*1)+(7*0)+(6*4)+(5*8)+(4*9)+(3*8)+(2*0)+(1*2)=134
134 % 10 = 4
So 104898-02-4 is a valid CAS Registry Number.

ASYMMETRIC HALOGENATION OF CAMPHOR-10-SULFONIC ACID DERIVED ESTERS: AN EFFICIENT NEW ROUTE TO ENANTIOMERICALLY PURE HALOHYDRINS AND EPOXIDES.
Oppolzer, Wolfgang,Dudfield, Philip
, p. 5037 - 5040 (2007/10/02)
Successive treatment of chiral esters 1 with LDA/Me3SiCl and NBS or NCS gave crystalline α-haloesters 3 which furnished halohydrins 4 and terminal epoxides 5 in high e.e..
