Check Digit Verification of cas no
The CAS Registry Mumber 107862-65-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,8,6 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 107862-65:
(8*1)+(7*0)+(6*7)+(5*8)+(4*6)+(3*2)+(2*6)+(1*5)=137
137 % 10 = 7
So 107862-65-7 is a valid CAS Registry Number.

Withasomnine has been prepared by rearrangement of 1-(3-chloropropyl)-cyclopropanol into 5,6-dihydro-4H-pyrrolo[1,2-b]pyrazole, followed by bromination and [NiCl2(dppp)]-catalyzed phenylation.
