129426-39-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129426-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,2 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129426-39:
(8*1)+(7*2)+(6*9)+(5*4)+(4*2)+(3*6)+(2*3)+(1*9)=137
137 % 10 = 7
So 129426-39-7 is a valid CAS Registry Number.
