121756-85-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121756-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,5 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121756-85:
(8*1)+(7*2)+(6*1)+(5*7)+(4*5)+(3*6)+(2*8)+(1*5)=122
122 % 10 = 2
So 121756-85-2 is a valid CAS Registry Number.

Impact of a Basal Nitro Group on the Density Characteristics of Select Peristylane Derivatives
Shen, Chien-Chang,Paquette, Leo A.
, p. 3324 - 3328 (2007/10/02)
Several peristilanes have been prepared that share in common a nitro group at C-9 of the basal cyclobutane ring.The synthetic entry of this class of molecules begins by Diels-Alder addition of nitro(trimethylsilyl)acetylene to tricyclo2,6
