161421-61-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161421-61-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,4,2 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 161421-61:
(8*1)+(7*6)+(6*1)+(5*4)+(4*2)+(3*1)+(2*6)+(1*1)=100
100 % 10 = 0
So 161421-61-0 is a valid CAS Registry Number.
