164020-60-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 164020-60-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,0,2 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 164020-60:
(8*1)+(7*6)+(6*4)+(5*0)+(4*2)+(3*0)+(2*6)+(1*0)=94
94 % 10 = 4
So 164020-60-4 is a valid CAS Registry Number.
