Check Digit Verification of cas no
The CAS Registry Mumber 148657-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,6,5 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 148657-23:
(8*1)+(7*4)+(6*8)+(5*6)+(4*5)+(3*7)+(2*2)+(1*3)=162
162 % 10 = 2
So 148657-23-2 is a valid CAS Registry Number.

The Still-Wittig rearrangement in the preparation of a synthetically useful 4C-hydroxymethyl-hex-2-enopyranoside
Wee,Zhang
, p. 325 - 334 (1993)
The Still-Wittig rearrangement of the stannyl-ether 9 is successfully carried out under optimal reaction conditions to give the 4C-hydroxymethyl-hex-2-enopyranoside 10 in good yields (70-74%).
