Check Digit Verification of cas no

The CAS Registry Mumber 40668-06-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,6 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40668-06:
(7*4)+(6*0)+(5*6)+(4*6)+(3*8)+(2*0)+(1*6)=112
112 % 10 = 2
So 40668-06-2 is a valid CAS Registry Number.

Accelerating Effect of Triazolyl and Related Heteroaryl Substituents on SNAr Reactions: Evidence of Hydrogen-Bond Stabilized Transition States

Qian, Wenyuan,Wang, Hao,Bartberger, Michael D.

, p. 12261 - 12268 (2015)

The remarkable accelerating effect of 1,2,3-triazolyl substituents on SNAr reactions has been investigated through systematic experiments and density functional theory calculations. The lone pair electrons of an ortho-triazolo substituent play
