Check Digit Verification of cas no

The CAS Registry Mumber 171070-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,0,7 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 171070-83:
(8*1)+(7*7)+(6*1)+(5*0)+(4*7)+(3*0)+(2*8)+(1*3)=110
110 % 10 = 0
So 171070-83-0 is a valid CAS Registry Number.

Access toward Fluorenone Derivatives through Solvent-Free Ruthenium Trichloride Mediated [2 + 2 + 2] Cycloadditions

Ye, Fei,Haddad, Mansour,Michelet, Véronique,Ratovelomanana-Vidal, Virginie

supporting information, p. 5612 - 5615 (2016/11/17)

An efficient and practical route for the preparation of highly substituted fluorenones and analogues via solvent-free ruthenium trichloride mediated [2 + 2 + 2] cycloaddition of α,-diynes and alkynes has been developed. This green chemistry approach involves a solventless and atom-economical catalytic process to generate densely functionalized fluorenones and related derivatives of high synthetic utility.
