75620-30-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75620-30-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,2 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75620-30:
(7*7)+(6*5)+(5*6)+(4*2)+(3*0)+(2*3)+(1*0)=123
123 % 10 = 3
So 75620-30-3 is a valid CAS Registry Number.

Note on Unusual Behaviour of 2,3,4,5-Tetrahydro-1,5-benzothiazepin-4-ones During Arylation
Ried, Walter,Sell, Gunther
, p. 1913 - 1916 (2007/10/02)
The 5-aryl-2,3,4,5-tetrahydro-1,5-benzothiazepines 3a-c have been synthesized by arylation of the corresponding 2,3,4,5-tetrahydro-1,5-benzothiazepin-4-ones 1.However, in some of these reactions the diaryl sulfides 4a,b and 5 were formed.
