89816-94-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89816-94-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,1 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89816-94:
(7*8)+(6*9)+(5*8)+(4*1)+(3*6)+(2*9)+(1*4)=194
194 % 10 = 4
So 89816-94-4 is a valid CAS Registry Number.
