705302-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 705302-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,5,3,0 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 705302-86:
(8*7)+(7*0)+(6*5)+(5*3)+(4*0)+(3*2)+(2*8)+(1*6)=129
129 % 10 = 9
So 705302-86-9 is a valid CAS Registry Number.
