89036-29-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89036-29-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,3 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89036-29:
(7*8)+(6*9)+(5*0)+(4*3)+(3*6)+(2*2)+(1*9)=153
153 % 10 = 3
So 89036-29-3 is a valid CAS Registry Number.
