Check Digit Verification of cas no

The CAS Registry Mumber 1417901-30-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,9,0 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1417901-30:
(9*1)+(8*4)+(7*1)+(6*7)+(5*9)+(4*0)+(3*1)+(2*3)+(1*0)=144
144 % 10 = 4
So 1417901-30-4 is a valid CAS Registry Number.

Catalytic Asymmetric Addition of Diorganozinc Reagents to Pyrazole-4,5-Diones and Indoline-2,3-Diones

Wang, Rong-Hui,Li, Ya-Ling,He, Hong-Jiao,Xiao, You-Cai,Chen, Fen-Er

, p. 4302 - 4306 (2021)

The catalytic enantioselective diorganozinc additions to cyclic diketones including pyrazolin-4,5-diones and isatins have been developed. In the presence of morpholine-containing chiral amino alcohol ligand, the corresponding chiral cyclic tertiary alcohols were produced in good to excellent yields (up to 97 %) and enantioselectivities (up to 95 % ee). The notable feature of this protocol includes its mild reaction conditions, Lewis acid additives free and broad functional group tolerance.
