147090-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147090-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,0,9 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 147090-13:
(8*1)+(7*4)+(6*7)+(5*0)+(4*9)+(3*0)+(2*1)+(1*3)=119
119 % 10 = 9
So 147090-13-9 is a valid CAS Registry Number.
