391257-53-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 391257-53-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,1,2,5 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 391257-53:
(8*3)+(7*9)+(6*1)+(5*2)+(4*5)+(3*7)+(2*5)+(1*3)=157
157 % 10 = 7
So 391257-53-7 is a valid CAS Registry Number.
