Check Digit Verification of cas no
The CAS Registry Mumber 942137-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,2,1,3 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 942137-21:
(8*9)+(7*4)+(6*2)+(5*1)+(4*3)+(3*7)+(2*2)+(1*1)=155
155 % 10 = 5
So 942137-21-5 is a valid CAS Registry Number.

An asymmetric synthesis of sulfobacin A
Sharma, Anubha,Gamre, Sunita,Chattopadhyay, Subrata
, p. 3705 - 3707 (2008/02/09)
A facile synthesis of sulfobacin A has been developed starting from (R)-cyclohexylideneglyceraldehyde (11). The key steps in the synthesis are the highly diastereocontrolled allylation of 11 and syn-selective reduction of a ketone derived from 11. The oth
