1239-11-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1239-11-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.Calculate Digit Verification of CAS Registry Number 1239-11:
(6*1)+(5*2)+(4*3)+(3*9)+(2*1)+(1*1)=58
58 % 10 = 8
So 1239-11-8 is a valid CAS Registry Number.
