The CAS Registry Mumber 24306-38-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,3,0 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 24306-38:
(7*2)+(6*4)+(5*3)+(4*0)+(3*6)+(2*3)+(1*8)=85
85 % 10 = 5
So 24306-38-5 is a valid CAS Registry Number.

The alkylation of disodium-(4-cyanisothiazole-3,5)-dithiolate 1 with α-chloro carbonyl compounds followed by Thorpe-Ziegler-cyclization yields the substituted 4-amino-thienoisothiazoles 3, which can be converted into the thieno-isothiazolo-1,4-thia
