620163-12-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 620163-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,1,6 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 620163-12:
(8*6)+(7*2)+(6*0)+(5*1)+(4*6)+(3*3)+(2*1)+(1*2)=104
104 % 10 = 4
So 620163-12-4 is a valid CAS Registry Number.
