Check Digit Verification of cas no

The CAS Registry Mumber 252051-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,0,5 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 252051-19:
(8*2)+(7*5)+(6*2)+(5*0)+(4*5)+(3*1)+(2*1)+(1*9)=97
97 % 10 = 7
So 252051-19-7 is a valid CAS Registry Number.

, p. 2463 - 2470 (2007/10/03)

New enantiomerically pure 3-naphthylaminomethylpyrrolidines (8), (9), (14) and (15) were obtained through simple steps starting from chiral 4- ethenylpyrrolidin-2-ones (2) and (3). On the other hand, starting from pyrrolidine (16), an epimerisation reacti
