134890-98-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134890-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,9 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134890-98:
(8*1)+(7*3)+(6*4)+(5*8)+(4*9)+(3*0)+(2*9)+(1*8)=155
155 % 10 = 5
So 134890-98-5 is a valid CAS Registry Number.
