137910-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137910-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,1 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137910-17:
(8*1)+(7*3)+(6*7)+(5*9)+(4*1)+(3*0)+(2*1)+(1*7)=129
129 % 10 = 9
So 137910-17-9 is a valid CAS Registry Number.
