Check Digit Verification of cas no
The CAS Registry Mumber 17948-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,4 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 17948-33:
(7*1)+(6*7)+(5*9)+(4*4)+(3*8)+(2*3)+(1*3)=143
143 % 10 = 3
So 17948-33-3 is a valid CAS Registry Number.

Mester, Iuliu,Reisch, Johannes,Rozsa, Zsuzsa,Szendrei, Kalman
, p. 77 - 79 (2007/10/02)
(+/-)-Rutacridone (1) was synthesized by condensation of 1,3-dihydroxy-10-methylacridone (3) with isoprene dibromide.As by-product the linear isomer (+/-)-isorutacridone (2) was also obtained.
