Check Digit Verification of cas no

The CAS Registry Mumber 301833-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,1,8,3 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 301833-44:
(8*3)+(7*0)+(6*1)+(5*8)+(4*3)+(3*3)+(2*4)+(1*4)=103
103 % 10 = 3
So 301833-44-3 is a valid CAS Registry Number.

Synthesis of C2-symmetrical chiral diamines: Diastereoselective addition to bis(1,3-oxazolidinyl)alkanes with Grignard reagents

Yamauchi, Takayasu,Higashiyama, Kimio,Kubo, Hajime,Ohmiya, Shigeru

, p. 3003 - 3015 (2007/10/03)

Asymmetric syntheses of C2-symmetrical chiral 1,4- and 1,5-diamines with stereogenic centers adjacent to the nitrogen atom have been accomplished. Chiral diamines were prepared by diastereoselective alkylations of bisoxazolidine, which was deri
