137380-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137380-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,8 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137380-49:
(8*1)+(7*3)+(6*7)+(5*3)+(4*8)+(3*0)+(2*4)+(1*9)=135
135 % 10 = 5
So 137380-49-5 is a valid CAS Registry Number.
