Check Digit Verification of cas no
The CAS Registry Mumber 12239-06-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 12239-06:
(7*1)+(6*2)+(5*2)+(4*3)+(3*9)+(2*0)+(1*6)=74
74 % 10 = 4
So 12239-06-4 is a valid CAS Registry Number.
