89335-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89335-13-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,3 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89335-13:
(7*8)+(6*9)+(5*3)+(4*3)+(3*5)+(2*1)+(1*3)=157
157 % 10 = 7
So 89335-13-7 is a valid CAS Registry Number.
