Check Digit Verification of cas no

The CAS Registry Mumber 1632174-97-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,2,1,7 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1632174-97:
(9*1)+(8*6)+(7*3)+(6*2)+(5*1)+(4*7)+(3*4)+(2*9)+(1*7)=160
160 % 10 = 0
So 1632174-97-0 is a valid CAS Registry Number.

Highly diastereoselective synthesis of chiral furans with a quaternary carbon substituent at the 2-position using 8-phenylmenthol as the chiral auxiliary

Katori, Aki,Sashihara, Yoshiaki,Iwamoto, Akihisa,Kojima, Satoshi,Yamamoto, Yohsuke

supporting information, p. 766 - 768 (2014/06/23)

The reaction of cis-4-oxo-2-pentenal and 8-phenylmenthyl 2-oxocyclopentane-1-carboxylate in the presence of a fluorinated cosolvent afforded the corresponding furan product with a high diastereoselectivity of up to 96% de. Other cyclic β-ketoesters reacted in a likewise diastereoselective manner.
