77152-09-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77152-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,5 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77152-09:
(7*7)+(6*7)+(5*1)+(4*5)+(3*2)+(2*0)+(1*9)=131
131 % 10 = 1
So 77152-09-1 is a valid CAS Registry Number.

, p. 5703 - 5706 (1985)
Treatment of optically active p-toluenesulfinamides (1) with thiols (2) in the presence of trifluoroacetic acid was found to give optically active p-toluenethiosulfinates (3) with predominant inversion of configuration.Stereospecificity of this reaction v
