3201-60-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3201-60-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,0 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3201-60:
(6*3)+(5*2)+(4*0)+(3*1)+(2*6)+(1*0)=43
43 % 10 = 3
So 3201-60-3 is a valid CAS Registry Number.
