394220-59-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 394220-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,4,2,2 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 394220-59:
(8*3)+(7*9)+(6*4)+(5*2)+(4*2)+(3*0)+(2*5)+(1*9)=148
148 % 10 = 8
So 394220-59-8 is a valid CAS Registry Number.
