77632-82-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77632-82-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,3 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77632-82:
(7*7)+(6*7)+(5*6)+(4*3)+(3*2)+(2*8)+(1*2)=157
157 % 10 = 7
So 77632-82-7 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.
