27429-80-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27429-80-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,2 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 27429-80:
(7*2)+(6*7)+(5*4)+(4*2)+(3*9)+(2*8)+(1*0)=127
127 % 10 = 7
So 27429-80-7 is a valid CAS Registry Number.

Thermal transformations of 2H-benzimidazole 1,3-dioxides represented by spiro[2H-benz-imidazole-2,1′-cyclohexane] 1,3-dioxide and its 5-nitro derivative were studied. Their heating resulted in reversible isomerization to spiro[3H-[2,1,4]benzoxadiazine-3,1
