141859-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141859-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,5 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141859-75:
(8*1)+(7*4)+(6*1)+(5*8)+(4*5)+(3*9)+(2*7)+(1*5)=148
148 % 10 = 8
So 141859-75-8 is a valid CAS Registry Number.
