117285-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117285-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,2,8 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117285-92:
(8*1)+(7*1)+(6*7)+(5*2)+(4*8)+(3*5)+(2*9)+(1*2)=134
134 % 10 = 4
So 117285-92-4 is a valid CAS Registry Number.

SYNTHESIS OF A CHIRAL SYNTHON FOR THE LACTONE PORTION OF COMPACTIN AND MEVINOLIN
Roth, Bruce D.,Roark, Howard, W.
, p. 1255 - 1258 (2007/10/02)
The stereoselective Michael addition of alcohols to 6-tosyloxymethyl-5,6-dihydro-2H-pyran-2-one afforded high yields of a key chiral synthon for the lactone portion of compactin and mevinolin.
