Check Digit Verification of cas no
The CAS Registry Mumber 69-91-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 6 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69-91:
(4*6)+(3*9)+(2*9)+(1*1)=70
70 % 10 = 0
So 69-91-0 is a valid CAS Registry Number.

Infrared spectrum, solubility, and ternary phase diagram of solubility indicated that 1,1,3,3-tetramethylbutylammonium salt (DL-TMB salt) of N-formyl-DL-α-phenylglycine is a conglomerate.In order to resolve DL-TMB salt efficiently, crystallization of D- and L-TMB salts was examined by free energy of critical nucleation in supersaturated solutions.Successive preferential crystallization of DL-TMB salt was experimented at 10 deg C for racemic solution in ethanol with the degree of supersaturation of 130percent, and D- and L-α-phenylglycine with 100percent optical purity were obtained from pure D- and L-TMB salts.
