Check Digit Verification of cas no

The CAS Registry Mumber 1354727-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,4,7,2 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1354727-81:
(9*1)+(8*3)+(7*5)+(6*4)+(5*7)+(4*2)+(3*7)+(2*8)+(1*1)=173
173 % 10 = 3
So 1354727-81-3 is a valid CAS Registry Number.

Synthesis of substituted α-tetralones and substituted 1-naphthols via regioselective ring expansion of 1-acyl-1-indanol skeleton

Yang, Te-Fang,Wang, Kuan-Yu,Li, Hsuan-Wei,Tseng, Yang-Chan,Lien, Tai-Chen

, p. 585 - 588 (2012/02/01)

Substituted 1-acyl-1-indanols were prepared using the corresponding readily commercially available substituted indanones as starting materials. Treatment of each 1-acyl-1-indanol derivative with sodium methoxide in hot methanol furnished a regiospecific 2-hydroxy-α-tetralone derivative, which was an α-keto rearrangement product. Each substituted 2-hydroxy-α-tetralone then underwent dehydration to afford the corresponding 1-naphthol derivative.
