135989-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135989-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,8 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135989-91:
(8*1)+(7*3)+(6*5)+(5*9)+(4*8)+(3*9)+(2*9)+(1*1)=182
182 % 10 = 2
So 135989-91-2 is a valid CAS Registry Number.

Synthesis of Self-Filled, Vaulted, and Intracavity-Functionalized Cappedophanes
Vinod, Thottumkara K.,Hart, Harold
, p. 5630 - 5640 (2007/10/02)
Two approaches to the synthesis of vaulted cappedophanes 3v are described.In the first, the walls and ceiling were prefabricated as in tetrathiol 5 (10a and 10b, Scheme II, are specific examples), which was then coupled with a m-terphenyl tetrabromide suc
