Check Digit Verification of cas no

The CAS Registry Mumber 68809-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,8,0 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68809-79:
(7*6)+(6*8)+(5*8)+(4*0)+(3*9)+(2*7)+(1*9)=180
180 % 10 = 0
So 68809-79-0 is a valid CAS Registry Number.

Similarity and Differences in the Regioselectivities of Thermal and Acid-Catalyzed van Alphen–Hüttel Rearrangements in the Series of 3,3-Diphenyl-3H-pyrazoles Containing Electron-Withdrawing Substituents on C4 and C5

Vasin,Razin,Bezrukova

, p. 1045 - 1054 (2018)

3,3-Diphenyl-3H-pyrazoles containing an electron-withdrawing substituent in the 5-position undergo van Alphen–Hüttel rearrangement with migration of one phenyl group to C4 on heating in an aprotic solvent (benzene, toluene), as well as on keepi
