129397-92-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129397-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,9 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129397-92:
(8*1)+(7*2)+(6*9)+(5*3)+(4*9)+(3*7)+(2*9)+(1*2)=168
168 % 10 = 8
So 129397-92-8 is a valid CAS Registry Number.
