1006689-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1006689-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,6,6,8 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1006689-40:
(9*1)+(8*0)+(7*0)+(6*6)+(5*6)+(4*8)+(3*9)+(2*4)+(1*0)=142
142 % 10 = 2
So 1006689-40-2 is a valid CAS Registry Number.
