141258-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141258-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,5 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 141258-90:
(8*1)+(7*4)+(6*1)+(5*2)+(4*5)+(3*8)+(2*9)+(1*0)=114
114 % 10 = 4
So 141258-90-4 is a valid CAS Registry Number.
