3118-85-2 Usage
Purification Methods
Crystallise D-gluconamide from EtOH or 1,2-dimethoxyethane. It mutarotates slowly and hydrolytically in aqueous solution from +30.7o to +13.8o in 80hours to give ammonium D-gluconate which recrystallises from 95% EtOH with m 153-154o and [] D +11.8o (c 3, H2O).

Check Digit Verification of cas no
The CAS Registry Mumber 3118-85-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,1 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3118-85:
(6*3)+(5*1)+(4*1)+(3*8)+(2*8)+(1*5)=72
72 % 10 = 2
So 3118-85-2 is a valid CAS Registry Number.
