137254-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137254-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,5 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137254-72:
(8*1)+(7*3)+(6*7)+(5*2)+(4*5)+(3*4)+(2*7)+(1*2)=129
129 % 10 = 9
So 137254-72-9 is a valid CAS Registry Number.
