191411-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191411-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,4,1 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 191411-50:
(8*1)+(7*9)+(6*1)+(5*4)+(4*1)+(3*1)+(2*5)+(1*0)=114
114 % 10 = 4
So 191411-50-4 is a valid CAS Registry Number.
