143809-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143809-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143809-98:
(8*1)+(7*4)+(6*3)+(5*8)+(4*0)+(3*9)+(2*9)+(1*8)=147
147 % 10 = 7
So 143809-98-7 is a valid CAS Registry Number.
