75400-64-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75400-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,0 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75400-64:
(7*7)+(6*5)+(5*4)+(4*0)+(3*0)+(2*6)+(1*4)=115
115 % 10 = 5
So 75400-64-5 is a valid CAS Registry Number.

Efficient synthesis of bis(heterocyclyl)methanes
Singh, Kamaljit,Sharma, Shivali,Sharma, Amit
experimental part, p. 3491 - 3496 (2011/09/16)
The reaction of pyrrole/furan aldehyde with Grignard reagent and pyrrole/N-methyl pyrrole in sequence allows efficient synthesis of a number of meso-elaborated bis(heterocyclyl)methanes, which are otherwise difficult to obtain through a direct aldehyde co
