109632-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109632-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,3 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109632-78:
(8*1)+(7*0)+(6*9)+(5*6)+(4*3)+(3*2)+(2*7)+(1*8)=132
132 % 10 = 2
So 109632-78-2 is a valid CAS Registry Number.
