137410-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137410-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,1 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137410-25:
(8*1)+(7*3)+(6*7)+(5*4)+(4*1)+(3*0)+(2*2)+(1*5)=104
104 % 10 = 4
So 137410-25-4 is a valid CAS Registry Number.
