108159-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108159-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,5 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 108159-77:
(8*1)+(7*0)+(6*8)+(5*1)+(4*5)+(3*9)+(2*7)+(1*7)=129
129 % 10 = 9
So 108159-77-9 is a valid CAS Registry Number.
