Check Digit Verification of cas no

The CAS Registry Mumber 83909-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,0 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83909-22:
(7*8)+(6*3)+(5*9)+(4*0)+(3*9)+(2*2)+(1*2)=152
152 % 10 = 2
So 83909-22-2 is a valid CAS Registry Number.

TfOH-Catalyzed Reaction of Bispropargyl Alcohols with 1,3-Dicarbonyl Compounds

Teng, Qinghu,Mo, Shikun,Pan, Jiankun,Wu, Na,Wang, Hengshan,Pan, Yingming

, p. 455 - 461 (2016)

A transition-metal-free efficient method for the preparation of 1,2,3-trisubstituted benzenes from bispropargyl alcohols and 1,3-dicarbonyl compounds has been developed. The reaction of bispropargyl alcohol with 1,3-dicarbonyl compound proceeds through [3,3]-rearrangement, 6π-electrocyclization, and unexpected Csp3-Csp2 regioselective σ-bond cleavage processes.
