Check Digit Verification of cas no
The CAS Registry Mumber 75472-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,7 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75472-91:
(7*7)+(6*5)+(5*4)+(4*7)+(3*2)+(2*9)+(1*1)=152
152 % 10 = 2
So 75472-91-2 is a valid CAS Registry Number.

Process for preparing diltiazem using a heterogeneous trifunctional catalyst
-
Page 3, (2008/06/13)
The present invention comprises a simplified synthesis of (+)-diltiazem through IE-PdOsW wherein IE is ion-exchanger, catalyzed three-component coupling reaction and Fe3+-exchanged clay catalyzed ring opening of sulfite with 2-aminothiophenol followed by cyclization as key steps.
