Check Digit Verification of cas no

The CAS Registry Mumber 1431318-87-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,3,1 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1431318-87:
(9*1)+(8*4)+(7*3)+(6*1)+(5*3)+(4*1)+(3*8)+(2*8)+(1*7)=134
134 % 10 = 4
So 1431318-87-4 is a valid CAS Registry Number.

Silver-catalyzed enantioselective desymmetrization: Facile access to spirolactone-pyrrolidines containing a spiro quaternary stereogenic center

Liu, Kang,Teng, Huai-Long,Yao, Lu,Tao, Hai-Yan,Wang, Chun-Jiang

supporting information, p. 2250 - 2253 (2013/06/05)

An unprecedented Ag(I)-catalyzed asymmetric desymmetrization of spiro cyclohexadienone lactones has been developed successfully, which performs well over a broad scope of substrates and provides a facile access to optically active spirolactone-pyrrolidines in high yields with excellent levels of diastereo-/enantioselectivities.
