89870-29-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89870-29-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,7 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89870-29:
(7*8)+(6*9)+(5*8)+(4*7)+(3*0)+(2*2)+(1*9)=191
191 % 10 = 1
So 89870-29-1 is a valid CAS Registry Number.

CONVERSION OF α ACETYLENIC ALCOHOLS INTO αβ UNSATURATED ALDEHYDES
Julia, Marc,Lefebvre, Christian
, p. 189 - 192 (2007/10/02)
Very mild conditions have been found for the efficient regioselective addition of phenylthiol to ethynyl carbinols.A biphasic aqueous acid hydrolysis then leads to αβ-unsaturated aldehydes.The Meyer-Schuster rearrangement is thus brought about in two steps.
