123268-67-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123268-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,6 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123268-67:
(8*1)+(7*2)+(6*3)+(5*2)+(4*6)+(3*8)+(2*6)+(1*7)=117
117 % 10 = 7
So 123268-67-7 is a valid CAS Registry Number.

SILOXY-WITTIG REARRANGEMENT: A NEW METHOD FOR DIASTEREOSELECTIVE PREPARATIONS OF 1,2-DIOL SYSTEMS
Nakai, Ei-ichi,Nakai, Takeshi
, p. 5409 - 5412 (2007/10/02)
A novel Wittig variant, termed "siloxy-Wittig rearrangement", has been developed which provides the half-silylated 1,2-diol systems with a high anti-diastereoselectivity.The unusual anti-selectivity is discussed on mechanistic grounds.
