Check Digit Verification of cas no

The CAS Registry Mumber 1621149-70-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,1,4 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1621149-70:
(9*1)+(8*6)+(7*2)+(6*1)+(5*1)+(4*4)+(3*9)+(2*7)+(1*0)=139
139 % 10 = 9
So 1621149-70-9 is a valid CAS Registry Number.

Asymmetric synthesis of spiro[isoxazolin-3,3'-oxindoles] via the catalytic 1,3-dipolar cycloaddition reaction of nitrile oxides

Lian, Xiangjin,Guo, Songsong,Wang, Gang,Lin, Lili,Liu, Xiaohua,Feng, Xiaoming

, p. 7703 - 7710 (2014)

A highly enantioselective 1,3-dipolar cycloaddition of nitrile oxides with 3-arylidene-oxindoles was realized by a chiral N,N'-dioxide-nickel(II) complex catalyst under mild reaction conditions. A series of spiro-isoxazoline-oxindole derivatives were obtained in moderate yields (up to 65%) with good regioselectivities (up to 99:1), excellent enantioselectivities (up to 99% ee), and exclusive diastereoselectivity as well.
