39549-55-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39549-55-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,5,4 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 39549-55:
(7*3)+(6*9)+(5*5)+(4*4)+(3*9)+(2*5)+(1*5)=158
158 % 10 = 8
So 39549-55-8 is a valid CAS Registry Number.
