126810-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126810-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,1 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126810-42:
(8*1)+(7*2)+(6*6)+(5*8)+(4*1)+(3*0)+(2*4)+(1*2)=112
112 % 10 = 2
So 126810-42-2 is a valid CAS Registry Number.

SYNTHESIS OF 2-SUBSTITUTED 3-FORMYL-5-METHOXYTETRAHYDROFURANS FROM 2,5-DIMETHOXYTETRAHYDROFURYL-3-CARBINOLS
Brezhnev, L. Yu.,Vartanyan, M. M.,Khandin, A. V.
, p. 132 - 134 (2007/10/02)
The acid-catalyzed rearrangement of 2,5-dimethoxytetrahydrofuryl-3-carbinol, obtained from 2,5-dimethoxy-3-formyltetrahydrofuran, gave the 2-substituted 3-formyl-5-methoxytetrahydrofuran.
