1239129-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1239129-17-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,1,2 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1239129-17:
(9*1)+(8*2)+(7*3)+(6*9)+(5*1)+(4*2)+(3*9)+(2*1)+(1*7)=149
149 % 10 = 9
So 1239129-17-9 is a valid CAS Registry Number.
