1620101-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1620101-20-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,0 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1620101-20:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*0)+(3*1)+(2*2)+(1*0)=83
83 % 10 = 3
So 1620101-20-3 is a valid CAS Registry Number.
