921754-08-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 921754-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,1,7,5 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 921754-08:
(8*9)+(7*2)+(6*1)+(5*7)+(4*5)+(3*4)+(2*0)+(1*8)=167
167 % 10 = 7
So 921754-08-7 is a valid CAS Registry Number.

Magnetic ends: By measuring the distribution of distances between two spin labels it is possible to quantify the flexibility of shape-persistent molecules (see picture). It is found that even the flexibility of short oligomers is described well by the wor
