1542980-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1542980-53-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,2,9,8 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1542980-53:
(9*1)+(8*5)+(7*4)+(6*2)+(5*9)+(4*8)+(3*0)+(2*5)+(1*3)=179
179 % 10 = 9
So 1542980-53-9 is a valid CAS Registry Number.
