88903-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88903-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,9,0 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88903-21:
(7*8)+(6*8)+(5*9)+(4*0)+(3*3)+(2*2)+(1*1)=163
163 % 10 = 3
So 88903-21-3 is a valid CAS Registry Number.
