Check Digit Verification of cas no
The CAS Registry Mumber 125263-13-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,6 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 125263-13:
(8*1)+(7*2)+(6*5)+(5*2)+(4*6)+(3*3)+(2*1)+(1*3)=100
100 % 10 = 0
So 125263-13-0 is a valid CAS Registry Number.

A FACILE SYNTHESIS OF 1,4-DIKETONES FROM ORGANOLITHIUM REAGENTS AND N,N,N',N'-TETRAMETHYLSUCCINAMIDE
Leung, Wai-Yee,LeGoff, Eugene
, p. 787 - 792 (2007/10/02)
The reaction of organolithium reagents (alkyl, aryl, heteroaryl) with N,N,N',N'-tetramethylsuccinamide at 0 deg C gives good yields of the corresponding 1,4-diketones.
