158498-10-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158498-10-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,4,9 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 158498-10:
(8*1)+(7*5)+(6*8)+(5*4)+(4*9)+(3*8)+(2*1)+(1*0)=173
173 % 10 = 3
So 158498-10-3 is a valid CAS Registry Number.
