Check Digit Verification of cas no
The CAS Registry Mumber 131452-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,5 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131452-03:
(8*1)+(7*3)+(6*1)+(5*4)+(4*5)+(3*2)+(2*0)+(1*3)=84
84 % 10 = 4
So 131452-03-4 is a valid CAS Registry Number.

, p. 1683 - 1686 (1990)
The dianion of 6,6-diphenylfulvene obtained by reduction with lithium metal was first characterized spectroscopically.Reduction of 6-dimethylamino-6-phenylfulvene also generated its dianion whose reactions with electrophiles led to 6-phenylfulvene derivat
