117923-79-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117923-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,2 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117923-79:
(8*1)+(7*1)+(6*7)+(5*9)+(4*2)+(3*3)+(2*7)+(1*9)=142
142 % 10 = 2
So 117923-79-2 is a valid CAS Registry Number.

Long-range 13C,13C spin-spin coupling constants in anisole and some derivatives
Schaefer, Ted,Penner, Glenn H.
, p. 1635 - 1640 (2007/10/02)
13C nuclear magnetic resonance chemical shifts and nJ(13C,13C) are reported for anisole and 16 of its derivatives, all enriched with 13C in the methoxy group.5J(13C,13C) is directly proportional to sin2θ, where θ is the an
