Check Digit Verification of cas no

The CAS Registry Mumber 52030-77-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,3 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 52030-77:
(7*5)+(6*2)+(5*0)+(4*3)+(3*0)+(2*7)+(1*7)=80
80 % 10 = 0
So 52030-77-0 is a valid CAS Registry Number.

Reaction of O-alkyl-N-substituted iminothiocarbonates with bromoacetyl bromide. A general method for the synthesis of 3-substituted 1,3-thiazolidine-2,4-diones

Imrich, Jan,Bernat, Juraj,Kristian, Pavol,Busov, Tatiana,Hocova, Slavka

, p. 432 - 436 (1996)

Reaction of sodium salts of O-methyl-N-substituted iminothiocaibonates with bromoacetyl bromide represents a new general method for preparation of 3-substituted 1,3-thiazolidine-2,4-diones in good yields and high purity. The structure of the synthesized products has been confirmed by 1H NMR, 13C NMR, IR and mass spectroscopy as well as by independent synthesis.
