Check Digit Verification of cas no
The CAS Registry Mumber 5446-75-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,4 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5446-75:
(6*5)+(5*4)+(4*4)+(3*6)+(2*7)+(1*5)=103
103 % 10 = 3
So 5446-75-3 is a valid CAS Registry Number.

PREPARATION D'ANHYDRIDES A PARTIR D'ACIDES CARBOXYLIQUES ET DE TETRACYANOETHYLENE
Voisin, Daniel,Gastambide, Bernard
, p. 1503 - 1504 (2007/10/02)
Symmetrical anhydrides are easily obtained at 20-80 deg C, with good yields, by action of tetracyanoethylene on organic carboxylic acids in benzene solutions containing a heteroaromatic nitrogen base or another base.
