27432-69-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27432-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,3 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27432-69:
(7*2)+(6*7)+(5*4)+(4*3)+(3*2)+(2*6)+(1*9)=115
115 % 10 = 5
So 27432-69-5 is a valid CAS Registry Number.
