Check Digit Verification of cas no

The CAS Registry Mumber 75072-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,0,7 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75072-80:
(7*7)+(6*5)+(5*0)+(4*7)+(3*2)+(2*8)+(1*0)=129
129 % 10 = 9
So 75072-80-9 is a valid CAS Registry Number.

Construction of 1-pyrroline skeletons by Lewis acid-mediated conjugate addition of vinyl azides

Zhu, Xu,Chiba, Shunsuke

, p. 2473 - 2476 (2016)

Lewis acid-mediated conjugate addition of vinyl azides to electron-deficient alkenes led to the efficient construction of 1-pyrroline skeletons. The reactions of vinyl azides with 3-alkylidene-2-oxoindolines afford 3′,4′-dihydrospiro[indoline-3,2′-pyrrol]-2-ones in a diastereoselective fashion, whereas those with dimethyl 2-alkylidenemalonates provide 4,5-dihydro-3H-pyrroles.
