89101-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89101-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,0 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89101-91:
(7*8)+(6*9)+(5*1)+(4*0)+(3*1)+(2*9)+(1*1)=137
137 % 10 = 7
So 89101-91-7 is a valid CAS Registry Number.
