634605-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 634605-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,6,0 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 634605-85:
(8*6)+(7*3)+(6*4)+(5*6)+(4*0)+(3*5)+(2*8)+(1*5)=159
159 % 10 = 9
So 634605-85-9 is a valid CAS Registry Number.
