Check Digit Verification of cas no
The CAS Registry Mumber 2179-92-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,7 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2179-92:
(6*2)+(5*1)+(4*7)+(3*9)+(2*9)+(1*2)=92
92 % 10 = 2
So 2179-92-2 is a valid CAS Registry Number.

Cyanide abstractions from benzyl isocyanides by Tri-n-Butyltin radical: An implication of imbalanced transition state and entropy control of reactivities
Kim, Sung Soo,Kim, Hoon,Yang, Ki Woong
, p. 5303 - 5306 (2007/10/03)
The relative rates and Hammett constants (ρ = 0.70) are immune from the temperature effects thus violating reactivity/selectivity principle. The polar TS can be classified as the 'imbalanced TS'. The substituents control the extent of the bond fissions end the rates are governed by the entropy term.
