78757-17-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78757-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,7,5 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 78757-17:
(7*7)+(6*8)+(5*7)+(4*5)+(3*7)+(2*1)+(1*7)=182
182 % 10 = 2
So 78757-17-2 is a valid CAS Registry Number.

Synthesis of some 4-thiazolidone derivatives from 4-(cyclo-3-alkenyl)thiosemicarbazones
Smolanka,Man'o,Krasnitskaya
, p. 457 - 458 (1981)
The reaction of 4-(cyclo-3-pentenyl)- and 4-(cyclo-3-hexenyl) thiosemicarbazones with chloroacetic acid gave 2-hydrazono derivatives of 3-cyclo-pentenyl (cyclohexenyl) thioazolid-4-one, the condensation of which with aromatic aldehydes gave 5-benzylidene
