75969-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75969-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,6 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75969-99:
(7*7)+(6*5)+(5*9)+(4*6)+(3*9)+(2*9)+(1*9)=202
202 % 10 = 2
So 75969-99-2 is a valid CAS Registry Number.

A NITROSAMINE ROUTE TO (+/-)-MACROSTOMINE
Wykypiel, Werner,Seebach, Dieter
, p. 1927 - 1930 (2007/10/02)
In a synthetic approach to macrostomine 1, both side chains of the isoquinoline nucleus are attached by high yield carbon carbon bond formation with lithiated nitrosamines (2b3a, 3c4a).
