108149-26-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108149-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,4 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 108149-26:
(8*1)+(7*0)+(6*8)+(5*1)+(4*4)+(3*9)+(2*2)+(1*6)=114
114 % 10 = 4
So 108149-26-4 is a valid CAS Registry Number.
