1321980-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1321980-67-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,1,9,8 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1321980-67:
(9*1)+(8*3)+(7*2)+(6*1)+(5*9)+(4*8)+(3*0)+(2*6)+(1*7)=149
149 % 10 = 9
So 1321980-67-9 is a valid CAS Registry Number.

Highly diastereoselective construction of substituted pyrrolidines: Formal synthesis of (-)-bulgecinine
Das, Biswanath,Kumar, Duddukuri Nandan
, p. 1285 - 1287 (2011)
A highly diastereoselective synthesis of substituted pyrrolidines has been achieved starting from nonchiral molecule, allyl bromide, or cis-but-2-ene-1,4-diol. The method involves the asymmetric epoxidation and endo-mode epoxide opening with azide nucleop
