161521-96-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161521-96-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,5,2 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 161521-96:
(8*1)+(7*6)+(6*1)+(5*5)+(4*2)+(3*1)+(2*9)+(1*6)=116
116 % 10 = 6
So 161521-96-6 is a valid CAS Registry Number.
