129409-97-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129409-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,0 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129409-97:
(8*1)+(7*2)+(6*9)+(5*4)+(4*0)+(3*9)+(2*9)+(1*7)=148
148 % 10 = 8
So 129409-97-8 is a valid CAS Registry Number.
