583872-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 583872-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,3,8,7 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 583872-99:
(8*5)+(7*8)+(6*3)+(5*8)+(4*7)+(3*2)+(2*9)+(1*9)=215
215 % 10 = 5
So 583872-99-5 is a valid CAS Registry Number.

Synthesis of enantiopure isoprene epoxides from (s)-lactic acid via 'dispoke' intermediates
Zhang, Daping,Bleasdale, Christine,Golding, Bernard T.,Watson, William P.
, p. 1141 - 1142 (2000)
'Dispoke protected lactate' derived from (S)-lactic acid was converted into the enantiopure isoprene epoxides (S)2-ethenyl-2-methyloxirane and (2R,2'S)-2-methylbioxirane.
