Check Digit Verification of cas no

The CAS Registry Mumber 1221689-24-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,6,8 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1221689-24:
(9*1)+(8*2)+(7*2)+(6*1)+(5*6)+(4*8)+(3*9)+(2*2)+(1*4)=142
142 % 10 = 2
So 1221689-24-2 is a valid CAS Registry Number.

A double donor-activated Ruthenium(VII) catalyst: Synthesis of enantiomerically pure THF-Diols

Cheng, Huan,Stark, Christian B. W.

, p. 1587 - 1590 (2010)

Chemical Equation Presented Double, double, no toll and trouble: Enantiomerically pure tetrahydrofurans are obtained with high position- and stereoselectivity through a ruthenium(Vll)-catalyzed oxidative cyclization of 5,6dihydroxy alkenes (see scheme TPAP = tetrapropylammonium perruthenate). A dual activation modifies the reactivity and increases the carbophilicity of the transition metal so that an otherwise unusual dioxygenation with perruthenate occurs.
