1298035-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1298035-50-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,8,0,3 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1298035-50:
(9*1)+(8*2)+(7*9)+(6*8)+(5*0)+(4*3)+(3*5)+(2*5)+(1*0)=173
173 % 10 = 3
So 1298035-50-3 is a valid CAS Registry Number.
