Check Digit Verification of cas no

The CAS Registry Mumber 141271-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,7 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 141271-93:
(8*1)+(7*4)+(6*1)+(5*2)+(4*7)+(3*1)+(2*9)+(1*3)=104
104 % 10 = 4
So 141271-93-4 is a valid CAS Registry Number.

Deduction of the Activation Parameters for Ring Expansion and Intersystem Crossing in Fluorinated Singlet Phenylnitrenes

Marcinek, Andrzej,Platz, Matthew S.

, p. 12674 - 12677 (1993)

The ratio (kexp + kisc)/kPYR was determined as a function of temperature for the singlet nitrenes derived from pentafluoro, 2,6 difluoro, and 2,4,6-trifluorophenyl azide where kPYR, kexp, and kisc are the absolute rate constants of reaction of the nitrene with pyridine, ring expansion, and intersystem crossing, respectively.Activation parameters were deduced for the three singlet nitrene processes.
