Check Digit Verification of cas no

The CAS Registry Mumber 178232-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,2,3 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 178232-05:
(8*1)+(7*7)+(6*8)+(5*2)+(4*3)+(3*2)+(2*0)+(1*5)=138
138 % 10 = 8
So 178232-05-8 is a valid CAS Registry Number.

An improved procedure for the enantioselective synthesis of (+)- and (-)-cis-4-hydroxyprolines and bulgecinines

Graziani, Lucia,Porzi, Gianni,Sandri, Sergio

, p. 1341 - 1346 (1996)

An efficient enantioselective synthesis of both the enantiomers of cis-4-hydroxy-proline and bulgecinine was accomplished starting from synthons 1 or 1'. The improved synthetic route to the aforesaid enantiomerically pure proline derivatives was established via a stereocontrolled double iodocyclization of 3(a,b) or 3'(a,b).
