Check Digit Verification of cas no
The CAS Registry Mumber 12039-52-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,3 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 12039-52:
(7*1)+(6*2)+(5*0)+(4*3)+(3*9)+(2*5)+(1*2)=70
70 % 10 = 0
So 12039-52-0 is a valid CAS Registry Number.
