127236-27-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127236-27-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,3 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127236-27:
(8*1)+(7*2)+(6*7)+(5*2)+(4*3)+(3*6)+(2*2)+(1*7)=115
115 % 10 = 5
So 127236-27-5 is a valid CAS Registry Number.

CYCLOADDITION REACTIONS OF HETEROAZADIENES: CYCLOADDITION OF 1-THIA-3-AZABUTADIENES WITH ELECTRON-POOR DIENOPHILES.
