925891-66-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 925891-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,5,8,9 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 925891-66:
(8*9)+(7*2)+(6*5)+(5*8)+(4*9)+(3*1)+(2*6)+(1*6)=213
213 % 10 = 3
So 925891-66-3 is a valid CAS Registry Number.

Novel synthesis of 1,3,4-thiadiazine derivatives and their cycloaddition reactions
Wardakhan, Wagnat W.
, p. 608 - 615 (2007/10/03)
4-Phenyl-3-thiosemicarbazide 1 reacted with the α-halocarbonyl compounds 2a, b to give the thiosemicarbazone derivatives 3a, b. The latter compounds underwent cyclization to the 1,3,4-thiadiazine derivatives 4a, b which underwent [2 + 4] cycloaddition rea
