1129-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1129-79-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1129-79:
(6*1)+(5*1)+(4*2)+(3*9)+(2*7)+(1*9)=69
69 % 10 = 9
So 1129-79-9 is a valid CAS Registry Number.
