153449-98-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153449-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,4,4 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 153449-98:
(8*1)+(7*5)+(6*3)+(5*4)+(4*4)+(3*9)+(2*9)+(1*8)=150
150 % 10 = 0
So 153449-98-0 is a valid CAS Registry Number.
