27489-28-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27489-28-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,8 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27489-28:
(7*2)+(6*7)+(5*4)+(4*8)+(3*9)+(2*2)+(1*8)=147
147 % 10 = 7
So 27489-28-7 is a valid CAS Registry Number.
