137351-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137351-03-2 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, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137351-03:
(8*1)+(7*3)+(6*7)+(5*3)+(4*5)+(3*1)+(2*0)+(1*3)=112
112 % 10 = 2
So 137351-03-2 is a valid CAS Registry Number.
