Check Digit Verification of cas no
The CAS Registry Mumber 34640-92-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,4 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34640-92:
(7*3)+(6*4)+(5*6)+(4*4)+(3*0)+(2*9)+(1*2)=111
111 % 10 = 1
So 34640-92-1 is a valid CAS Registry Number.

-
Example 9, (2010/02/14)
The invention relates to a method for production of acetamide acetals of formula (I), where R1 and R2 independently = C1-C6 alkyl, phenyl or benzyl, or together form a C2-C6 alkylene and R3 and R4 independently = H, C1-C6 alkyl or benzyl, or together form a C3-C6 alkylene, whereby a glyoxylate ester diacetal of formula (II), in which R1 and R2 are as above and R5 = C1-C4 alkyl, is reacted with DMF or an amine of formula (III) NHR4R5, where R4 and R5 are as above, in the presence of 0.005 to 3 Mol %, based on the amine of formula (III), of an alcoholate of formula (IV) XOC1-C4, where X = Na, K or Li, at a reaction temperature of 0 to 100 °C to give the corresponding compound of formula (I).
