137351-48-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137351-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,5 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137351-48:
(8*1)+(7*3)+(6*7)+(5*3)+(4*5)+(3*1)+(2*4)+(1*8)=125
125 % 10 = 5
So 137351-48-5 is a valid CAS Registry Number.
