129491-72-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129491-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,9 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129491-72:
(8*1)+(7*2)+(6*9)+(5*4)+(4*9)+(3*1)+(2*7)+(1*2)=151
151 % 10 = 1
So 129491-72-1 is a valid CAS Registry Number.
