Check Digit Verification of cas no
The CAS Registry Mumber 890652-03-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,6,5 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 890652-03:
(8*8)+(7*9)+(6*0)+(5*6)+(4*5)+(3*2)+(2*0)+(1*3)=186
186 % 10 = 6
So 890652-03-6 is a valid CAS Registry Number.

Complete assignment of 1H and 13C NMR chemical shifts and J(1H/1H and 1H/19F) coupling constants for 22 1-phenyl-1H-pyrazoles' derivates were performed using the concerted application of 1H 1D and 1H, 13C 2D gs-HSQC and gs-HMBC experiments. All 1-phenyl-1H-pyrazoles' derivatives were synthesized as described by Finar and co-workers. The formylated 1-phenyl-1H-pyrazoles' derivatives were performed under Duff's conditions. Copyright
