870614-82-7 Usage

Uses

4-Dehydroxy-4-dimethylhydroxysilyl Entecavir is an impurity of Entecavir (E558900).

Check Digit Verification of cas no

The CAS Registry Mumber 870614-82-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,6,1 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 870614-82:
(8*8)+(7*7)+(6*0)+(5*6)+(4*1)+(3*4)+(2*8)+(1*2)=177
177 % 10 = 7
So 870614-82-7 is a valid CAS Registry Number.
