161722-19-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161722-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,7,2 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161722-19:
(8*1)+(7*6)+(6*1)+(5*7)+(4*2)+(3*2)+(2*1)+(1*9)=116
116 % 10 = 6
So 161722-19-6 is a valid CAS Registry Number.
