108653-89-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108653-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,6,5 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 108653-89:
(8*1)+(7*0)+(6*8)+(5*6)+(4*5)+(3*3)+(2*8)+(1*9)=140
140 % 10 = 0
So 108653-89-0 is a valid CAS Registry Number.
