134891-24-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134891-24-0 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 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134891-24:
(8*1)+(7*3)+(6*4)+(5*8)+(4*9)+(3*1)+(2*2)+(1*4)=140
140 % 10 = 0
So 134891-24-0 is a valid CAS Registry Number.
