1171112-06-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1171112-06-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,1,1,1 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1171112-06:
(9*1)+(8*1)+(7*7)+(6*1)+(5*1)+(4*1)+(3*2)+(2*0)+(1*6)=93
93 % 10 = 3
So 1171112-06-3 is a valid CAS Registry Number.

Synthesis of higher helicenes via olefin metathesis and C-H activation
Cote, Julie,Collins, Shawn K.
experimental part, p. 1499 - 1505 (2009/12/08)
Functionalized heterohelicenes were prepared using sequential olefin metathesis and direct arylation reactions. Functionalization via C-H activation always occurs at the least hindered position of the [5]helicene carbon skeleton. Attempts at blocking the
