Check Digit Verification of cas no

The CAS Registry Mumber 1443041-72-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,0,4 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1443041-72:
(9*1)+(8*4)+(7*4)+(6*3)+(5*0)+(4*4)+(3*1)+(2*7)+(1*2)=122
122 % 10 = 2
So 1443041-72-2 is a valid CAS Registry Number.

Diastereo- and enantioselective construction of oxindole-fused spirotetrahydrofuran scaffolds through palladium-catalyzed asymmetric [3+2] cycloaddition of vinyl cyclopropanes and isatins

Mei, Liang-Yong,Wei, Yin,Xu, Qin,Shi, Min

, p. 3544 - 3556 (2013/07/26)

A novel asymmetric formal [3+2] cycloaddition of vinyl cyclopropanes and isatins in the presence of Pd2(dba)3 and the chiral imidazoline-phosphine ligand (aS,R,R)-L3 has been developed, affording the corresponding highly functionalized oxindole-fused spirotetrahydrofuran frameworks in good yields along with good diastereo- and high enantioselectivities under mild conditions.
