70090-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70090-75-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,0,9 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70090-75:
(7*7)+(6*0)+(5*0)+(4*9)+(3*0)+(2*7)+(1*5)=104
104 % 10 = 4
So 70090-75-4 is a valid CAS Registry Number.

, p. 355 - 370 (2007/10/02)
The acid catalyzed dienol-benzene rearrangement of 3- and 5-methyl-substituted (2'-propinyl)cyclohexadienols has been investigated.Treatment of the dienols with CF3COOH in CCl4 yields allenyl- and (2'-propinyl)benzenes via - and -sigmatropic rea
