40989-88-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40989-88-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,8 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40989-88:
(7*4)+(6*0)+(5*9)+(4*8)+(3*9)+(2*8)+(1*8)=156
156 % 10 = 6
So 40989-88-6 is a valid CAS Registry Number.
