1542980-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1542980-49-3 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, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1542980-49:
(9*1)+(8*5)+(7*4)+(6*2)+(5*9)+(4*8)+(3*0)+(2*4)+(1*9)=183
183 % 10 = 3
So 1542980-49-3 is a valid CAS Registry Number.
