875535-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 875535-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,5,3 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 875535-12:
(8*8)+(7*7)+(6*5)+(5*5)+(4*3)+(3*5)+(2*1)+(1*2)=199
199 % 10 = 9
So 875535-12-9 is a valid CAS Registry Number.
