925913-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 925913-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,5,9,1 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 925913-21:
(8*9)+(7*2)+(6*5)+(5*9)+(4*1)+(3*3)+(2*2)+(1*1)=179
179 % 10 = 9
So 925913-21-9 is a valid CAS Registry Number.
