Check Digit Verification of cas no

The CAS Registry Mumber 75516-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,1 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75516-90:
(7*7)+(6*5)+(5*5)+(4*1)+(3*6)+(2*9)+(1*0)=144
144 % 10 = 4
So 75516-90-4 is a valid CAS Registry Number.

X=Y-ZH SYSTEMS AS POTENTIAL 1,3-DIPOLES. PART 17. SEQUENTIAL MICHAEL ADDITION-5-ENDO-TRIG CYCLISATION OF ARYLIDENE IMINES OF Α-AMINO ACID ESTERS

Grigg, Ronald,Kemp, James,Malone, John F.,Rajviroongit, Shuleewan,Tangthongkum, Anant

, p. 5361 - 5374 (2007/10/02)

Imines of α-amino acid esters undergo regiospecific Michael addition to methyl acrylate or acrylonitrile in good yield in benzene at 25 degC catalysed by benzyltrimethylammonium methoxide (BTAM).The Michael adducts cyclise to a mixture of two stereoisomer

5-Endo-Trig Cyclisation and 1,3-Anionic Cycloaddition in Arylimine Derivatives of α-Amino Acid Esters

Grigg, Ronald,Kemp, James,Malone, John,Tangthongkum, Anant

, p. 648 - 650 (2007/10/02)

Michael adducts of imines of α-amino acid esters are converted into a mixture of two stereoisomeric pyrrolidines by benzyltrimethylammonium methoxide (BTAM) apparently by a 5-endo-trig cyclisation.
