Check Digit Verification of cas no
The CAS Registry Mumber 81216-95-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,1 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81216-95:
(7*8)+(6*1)+(5*2)+(4*1)+(3*6)+(2*9)+(1*5)=117
117 % 10 = 7
So 81216-95-7 is a valid CAS Registry Number.

Direction of 3-bromothiophene acylation with succinyl chloride
Smirnov,Afanas'Ev,Prostakishin,Belen'Kii
, p. 386 - 391 (2013)
In the reaction of 3-bromothiophene with succinyl chloride in the presence of AlCl3, a mixture of three isomeric dibromo-substituted 1,4-di(2-thienyl)butane-1,4-diones was formed. The main component was the unsymmetrical 1-(3-bromo-2-thienyl)-4-(4-bromo-2-thienyl)butane-1,4-dione rather than 1,4-di-(3-bromo-2-thienyl)butane-1,4-dione expected according to the orientation rules.
