357154-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 357154-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,1,5 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 357154-20:
(8*3)+(7*5)+(6*7)+(5*1)+(4*5)+(3*4)+(2*2)+(1*0)=142
142 % 10 = 2
So 357154-20-2 is a valid CAS Registry Number.

Machetti, Fabrizio,Cordero, Franca M,De Sarlo, Francesco,Brandi, Alberto
, p. 4995 - 4998 (2007/10/03)
A new synthesis of both enantiomers of protected 4-oxopipecolic acid was achieved in six steps via 1,3-dipolar cycloaddition of C-ethoxycarbonyl N-(1R)-phenylethylnitrone to but-3-en-1-ol.
