123767-09-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123767-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,6 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123767-09:
(8*1)+(7*2)+(6*3)+(5*7)+(4*6)+(3*7)+(2*0)+(1*9)=129
129 % 10 = 9
So 123767-09-9 is a valid CAS Registry Number.
