Check Digit Verification of cas no

The CAS Registry Mumber 54808-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,0 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54808-41:
(7*5)+(6*4)+(5*8)+(4*0)+(3*8)+(2*4)+(1*1)=132
132 % 10 = 2
So 54808-41-2 is a valid CAS Registry Number.

Multicomponent cis- and trans-Aziridinatons in the Syntheses of All Four Stereoisomers of Sphinganine

Zhou, Yubai,Mukherjee, Munmun,Gupta, Anil K.,Wulff, William D.

, p. 2230 - 2233 (2017)

All four stereoisomers of sphinganine can be synthesized by a multicomponent aziridination of an aldehyde, an amine and an α-diazo carbonyl compound mediated by a BOROX catalyst with high asymmetric induction (≥96% ee). The threo isomers are available from ring-opening of cis-aziridines by an oxygen nucleophile with inversion at the C-3 position and the erythro-isomers are likewise available from trans-aziridines.
