Calculate Digit Verification of CAS Registry Number 121999-16:
(8*1)+(7*2)+(6*1)+(5*9)+(4*9)+(3*9)+(2*1)+(1*6)=144
144 % 10 = 4
So 121999-16-4 is a valid CAS Registry Number.

Synthesis of semicarbazones and thiosemicarbazones of 1-(2-benzothiazolon-3-yl) propanones

Antonova,Simov,Kalcheva

, p. 1294 - 1296 (1990)

Semi- and thiosemicarbazones were synthesized by the reaction of 1-(2-benzothiazolon-3-yl)propanones with semi- and thiosemicarbazide. These compounds are more active in stimulating plant growth than the starting propanones.
