20508-12-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20508-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,0 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20508-12:
(7*2)+(6*0)+(5*5)+(4*0)+(3*8)+(2*1)+(1*2)=67
67 % 10 = 7
So 20508-12-7 is a valid CAS Registry Number.
