Check Digit Verification of cas no
The CAS Registry Mumber 156245-57-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,2,4 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156245-57:
(8*1)+(7*5)+(6*6)+(5*2)+(4*4)+(3*5)+(2*5)+(1*7)=137
137 % 10 = 7
So 156245-57-7 is a valid CAS Registry Number.

Azines and imines of 4- and 5-t-Bu-pyrrole-2-aldehyde. A useful synthesis of the aldehydes
Mueller-Westerhoff,Swiegers
, p. 1389 - 1393 (1994)
The preparation of 4- and 5-t-Bu-pyrrole-2-aldehyde can be brought about in a high yield and purity using Vilsmeier-Haack type reactions as conclusions to reaction sequences involving a 1-benzenesulfonyl directing group on pyrrole (4-substitution) or the formamidinium salt of pyrrole (5- substitution). Azines/imines were prepared and characterised.
