Check Digit Verification of cas no
The CAS Registry Mumber 123775-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,7 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123775-44:
(8*1)+(7*2)+(6*3)+(5*7)+(4*7)+(3*5)+(2*4)+(1*4)=130
130 % 10 = 0
So 123775-44-0 is a valid CAS Registry Number.

α-Methoxylation of Unsaturated Carbonyl Compounds
Feuerer, Albert,Severin, Theodor
, p. 6026 - 6029 (2007/10/02)
α-Methoxylation of enals or enones can be performed in high yield by a simple one-pot reaction sequence: Bromination of unsaturated hydrazones, HBr-elimination, and addition of methanol leads to the formation of β-bromo-α-methoxy hydrazones (11), which af
