13854-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13854-94-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,5 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13854-94:
(7*1)+(6*3)+(5*8)+(4*5)+(3*4)+(2*9)+(1*4)=119
119 % 10 = 9
So 13854-94-9 is a valid CAS Registry Number.
