Check Digit Verification of cas no
The CAS Registry Mumber 1632-19-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1632-19:
(6*1)+(5*6)+(4*3)+(3*2)+(2*1)+(1*9)=65
65 % 10 = 5
So 1632-19-5 is a valid CAS Registry Number.

A general method for the synthesis of N-unsubstituted 3,4-diarylpyrrole-2, 5-dicarboxylates

experimental part, p. 1105 - 1122 (2010/09/16)
A general method for the synthesis of N-unsubstituted 3,4-diarylpyrrole-2, 5-dicarboxylates (3) has been developed. The key reactions involved are the Hinsberg-type synthesis of dimethyl N-benzyl-3,4-dihydroxypyrrole-2,5- dicarboxylate (6) followed by palladium-catalyzed Suzuki-Miyaura coupling of its bis-triflate derivative (7). The N-benzyl protecting group of the resulting 3,4-diaryl pyrrole-2,5-dicarboxyl ates (8) is cleanly removed under hydrogenolytic or solvolytic conditions.
