75684-07-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75684-07-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,8 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75684-07:
(7*7)+(6*5)+(5*6)+(4*8)+(3*4)+(2*0)+(1*7)=160
160 % 10 = 0
So 75684-07-0 is a valid CAS Registry Number.

Thomas, James B.,Brieaddy, Lawrence E.,Boldt, Karl G.,Perretta, Carin,Carroll, F. Ivy
, p. 1481 - 1484 (2008/02/08)
An efficient synthesis of racemic bremazocine hydrochloride salt was developed. The racemic material was resolved using (+)- and (-)-3- bromocamphorsulfonic acid ammonium salt to give optically pure samples of (-)- and (+)-bremazocine. Georg Thieme Verlag
