4074-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4074-20-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,7 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4074-20:
(6*4)+(5*0)+(4*7)+(3*4)+(2*2)+(1*0)=68
68 % 10 = 8
So 4074-20-8 is a valid CAS Registry Number.

REVERSAL OF THE REGIOSELECTIVITY OF THE BIRCH REDUCTION OF XYLENES
Epling, Gary A.,Florio, Emily
, p. 1469 - 1472 (2007/10/02)
The "Photo-Birch" reduction of o-, m-, and p-xylene, using NaBH4, 1,3-dicyanobenzene, and photolysis, gives 1,4-dienes as products.The regioselectivity of these reactions is greatly different from the normal Birch reduction.
