161392-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161392-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,3,9 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 161392-68:
(8*1)+(7*6)+(6*1)+(5*3)+(4*9)+(3*2)+(2*6)+(1*8)=133
133 % 10 = 3
So 161392-68-3 is a valid CAS Registry Number.
