109643-29-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109643-29-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,4 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109643-29:
(8*1)+(7*0)+(6*9)+(5*6)+(4*4)+(3*3)+(2*2)+(1*9)=130
130 % 10 = 0
So 109643-29-0 is a valid CAS Registry Number.
