1267000-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1267000-76-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,0,0 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1267000-76:
(9*1)+(8*2)+(7*6)+(6*7)+(5*0)+(4*0)+(3*0)+(2*7)+(1*6)=129
129 % 10 = 9
So 1267000-76-9 is a valid CAS Registry Number.
