53798-51-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53798-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,9 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 53798-51:
(7*5)+(6*3)+(5*7)+(4*9)+(3*8)+(2*5)+(1*1)=159
159 % 10 = 9
So 53798-51-9 is a valid CAS Registry Number.

SYNTHETIC APPROACHES TOWARD VERRUCARIN A. CHIRAL SYNTHESIS OF (-)-VERRUCARINOLACTONE
Tomioka, Kiyoshi,Sato, Fuminori,Koga, Kenji
, p. 311 - 316 (2007/10/02)
(-)-Verrucarinolactone ((2S,3R)-2,5-dihydroxy-3-methylvaleric acid δ-lactone) (4) was synthesized stereoselectively from an optically active butyrolactone ((S)-γ-trityloxymethyl-γ-butyrolactone) (6) as a chiral synthon.
