Check Digit Verification of cas no
The CAS Registry Mumber 51849-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,8,4 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51849-23:
(7*5)+(6*1)+(5*8)+(4*4)+(3*9)+(2*2)+(1*3)=131
131 % 10 = 1
So 51849-23-1 is a valid CAS Registry Number.

REACTION OF TRIMETHYLSILYL DERIVATIVES WITH MELDRUM'S ACID : A NEW AND EASY MONOFUNCTIONALIZATION OF MALONIC ACID
Rigo, B.,Fasseur, D.,Cauliez, P.,Couturier, D.
, p. 3073 - 3076 (2007/10/02)
Treament of Meldrum's acid with silylated derivatives (amines, lactams or alcohols) yields very easily monofunctionalized malonic silyl esters.Hydrolysis of these silyl esters leads to the corresponding monoacids with a very good yield.
