108591-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108591-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,5,9 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 108591-67:
(8*1)+(7*0)+(6*8)+(5*5)+(4*9)+(3*1)+(2*6)+(1*7)=139
139 % 10 = 9
So 108591-67-9 is a valid CAS Registry Number.
