88521-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88521-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,5,2 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88521-41:
(7*8)+(6*8)+(5*5)+(4*2)+(3*1)+(2*4)+(1*1)=149
149 % 10 = 9
So 88521-41-9 is a valid CAS Registry Number.
