13904-14-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13904-14-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,0 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13904-14:
(7*1)+(6*3)+(5*9)+(4*0)+(3*4)+(2*1)+(1*4)=88
88 % 10 = 8
So 13904-14-8 is a valid CAS Registry Number.
