74989-85-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74989-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,8 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74989-85:
(7*7)+(6*4)+(5*9)+(4*8)+(3*9)+(2*8)+(1*5)=198
198 % 10 = 8
So 74989-85-8 is a valid CAS Registry Number.
