154928-39-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 154928-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,9,2 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 154928-39:
(8*1)+(7*5)+(6*4)+(5*9)+(4*2)+(3*8)+(2*3)+(1*9)=159
159 % 10 = 9
So 154928-39-9 is a valid CAS Registry Number.
