147502-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147502-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,5,0 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 147502-20:
(8*1)+(7*4)+(6*7)+(5*5)+(4*0)+(3*2)+(2*2)+(1*0)=113
113 % 10 = 3
So 147502-20-3 is a valid CAS Registry Number.
