372971-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 372971-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,2,9,7 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 372971-69:
(8*3)+(7*7)+(6*2)+(5*9)+(4*7)+(3*1)+(2*6)+(1*9)=182
182 % 10 = 2
So 372971-69-2 is a valid CAS Registry Number.

Dehydration rearrangements of derivatives of methylenedihydro-benzofuran - A new path to substituted benzofurans
Ukhin,Belousova,Orlova,Korobov,Borodkin
, p. 1174 - 1179 (2007/10/03)
When heated with acidic agents derivatives of 3-amino-2-(hydroxydialkylmethyl)methylene-2,3-dihydrobenzofuran undergo rapid dehyration and rearrangement to substituted 2-alkenyl-3-aminobenzofurans.
