137503-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137503-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,0 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137503-74:
(8*1)+(7*3)+(6*7)+(5*5)+(4*0)+(3*3)+(2*7)+(1*4)=123
123 % 10 = 3
So 137503-74-3 is a valid CAS Registry Number.
