74781-09-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74781-09-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,8 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74781-09:
(7*7)+(6*4)+(5*7)+(4*8)+(3*1)+(2*0)+(1*9)=152
152 % 10 = 2
So 74781-09-2 is a valid CAS Registry Number.

A NEW SYNTHESIS OF α,β-UNSATURATED KETONES. ALLYLIC ALKYLATION OF 1-ISOCYANO-1-TOSYLALKENES
Moskal, Janusz,Leusen, Albert M. van
, p. 2585 - 2588 (2007/10/02)
Ketones (1) are homologated to enones 2 by alkylating (introduction of R3) the condensation products 4 (derived from 1 and tosylmethyl isocyanide), followed by acid catalyzed hydrolysis.
