85931-94-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 85931-94-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,3 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85931-94:
(7*8)+(6*5)+(5*9)+(4*3)+(3*1)+(2*9)+(1*4)=168
168 % 10 = 8
So 85931-94-8 is a valid CAS Registry Number.

Stereochemistry of the Formation of 4-Alkoxyimino-5,6-dihydro-6-alkoxyaminopyrimidin-2(1H)-ones from Cytosines and Hydroxylamines

Atkins, Paul J.,Hall, C. Dennis

, p. 155 - 160 (2007/10/02)

High resolution 1H and 19F n.m.r. data together with deuterium labelling studies are presented which reveal that the addition of hydroxylamines across the 5,6-double bond of cytosines is predominantly trans.The 4-alkoxyimino-5,6-dihydro-6-alkoxyaminopyrimidin-2(1H)-one products show syn/anti isomerism about the 4-alkoxyimino-group dependent on the substituent at N(3) (H or Me, respectively) and conformational changes throughout the molecules which are dependent on the substituents at N(1) (H or Me) and C(5) (H or F).
