Check Digit Verification of cas no

The CAS Registry Mumber 57969-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,6 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57969-70:
(7*5)+(6*7)+(5*9)+(4*6)+(3*9)+(2*7)+(1*0)=187
187 % 10 = 7
So 57969-70-7 is a valid CAS Registry Number.

Studies toward the Synthesis of Hepta- peri -heptabenzo-[7]circulene

Yang, Xuejin,Miao, Qian

, p. 2091 - 2094 (2016)

In this letter we report the synthesis and characterization of two new heptagon-embedded nonplanar π-conjugated molecules, which can be regarded as synthetic precursors of hepta-peri-heptabenzo-[7]circulene, an interesting but unknown polycyclic arene wit
