27320-24-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27320-24-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,3,2 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 27320-24:
(7*2)+(6*7)+(5*3)+(4*2)+(3*0)+(2*2)+(1*4)=87
87 % 10 = 7
So 27320-24-7 is a valid CAS Registry Number.
