141258-29-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141258-29-9 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, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141258-29:
(8*1)+(7*4)+(6*1)+(5*2)+(4*5)+(3*8)+(2*2)+(1*9)=109
109 % 10 = 9
So 141258-29-9 is a valid CAS Registry Number.
