152139-46-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152139-46-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,1,3 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 152139-46:
(8*1)+(7*5)+(6*2)+(5*1)+(4*3)+(3*9)+(2*4)+(1*6)=113
113 % 10 = 3
So 152139-46-3 is a valid CAS Registry Number.

A convenient synthesis of enantiomerically pure aldopentono-1,4- thiolactones is described. Thus, 4-thio-D-ribono-1,4-lactone (12) has been prepared from D-gulono-1,4-lactone (1), via its 2,3-O-isopropylidene derivative 3. The 5,6-glycol system of 3 was o
