Check Digit Verification of cas no
The CAS Registry Mumber 4408-82-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4408-82:
(6*4)+(5*4)+(4*0)+(3*8)+(2*8)+(1*2)=86
86 % 10 = 6
So 4408-82-6 is a valid CAS Registry Number.

Highly regioselective lithiation of inter-ring carbon of bis(thien-2yl)methane: a general meso-elaboration protocol
Singh, Kamaljit,Sharma, Amit
experimental part, p. 3682 - 3686 (2010/07/04)
Bis(thien-2yl)methane is regioselectively lithiated at the inter-ring methylene carbon using dimsyl anion in THF at 0 °C; quenching with appropriate electrophile furnishes meso-elaborated derivatives, exclusively with synthetic advantage.
