Check Digit Verification of cas no
The CAS Registry Mumber 161935-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,9,3 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161935-19:
(8*1)+(7*6)+(6*1)+(5*9)+(4*3)+(3*5)+(2*1)+(1*9)=139
139 % 10 = 9
So 161935-19-9 is a valid CAS Registry Number.
