862970-58-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 862970-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,9,7 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 862970-58:
(8*8)+(7*6)+(6*2)+(5*9)+(4*7)+(3*0)+(2*5)+(1*8)=209
209 % 10 = 9
So 862970-58-9 is a valid CAS Registry Number.

, p. 3805 - 3815 (2007/10/03)
Novel N-phenyl aromatic polyureas containing bis[(N,N′- diphenylureylene)methyl]silane units in the skeleton were designed as a new type of photodegradable polymer. These materials were successfully prepared in 88-93% yields by copolymerization of bis(ani
