Check Digit Verification of cas no

The CAS Registry Mumber 57764-45-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,6 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57764-45:
(7*5)+(6*7)+(5*7)+(4*6)+(3*4)+(2*4)+(1*5)=161
161 % 10 = 1
So 57764-45-1 is a valid CAS Registry Number.

Most Efficient Intramolecular General Acid Catalysis of Acetal Hydrolysis by the Carboxy Group

Kirby, Anthony J.,Parkinson, Adrian

, p. 707 - 708 (2007/10/02)

The hydrolysis of 4-methoxymethoxybenzisoxazole-3-carboxylic acid (halflife 31 s at 39 deg C) is the fastest measured for a methoxymethyl acetal: catalysis by the neighbouring CO2H group is facilitated by a strong intramolecular hydrogen bond.
