Check Digit Verification of cas no

The CAS Registry Mumber 327626-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,7,6,2 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 327626-37:
(8*3)+(7*2)+(6*7)+(5*6)+(4*2)+(3*6)+(2*3)+(1*7)=149
149 % 10 = 9
So 327626-37-9 is a valid CAS Registry Number.

Novel use of imidazolium ylides in an efficient synthesis of 2-substituted imidazoles

Hlasta, Dennis J.

, p. 157 - 159 (2007/10/03)

equation presented A new reaction of imidazoles was discovered involving the formation of an imidazolium ylide, which on trapping with various electrophiles afforded diverse 2-substituted imidazoles. The facile, convenient reaction conditions when compared to the existing procedures make this reaction the method of choice in the preparation of 2-substituted imidazoles. Moreover, the reaction differs from the reported methods since the products (viz., 1) contain an α-substituent that is transformed by solvolysis chemistry into further functionalized derivatives.
