109386-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109386-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,3,8 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109386-99:
(8*1)+(7*0)+(6*9)+(5*3)+(4*8)+(3*6)+(2*9)+(1*9)=154
154 % 10 = 4
So 109386-99-4 is a valid CAS Registry Number.
