1239694-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1239694-35-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,6,9 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1239694-35:
(9*1)+(8*2)+(7*3)+(6*9)+(5*6)+(4*9)+(3*4)+(2*3)+(1*5)=189
189 % 10 = 9
So 1239694-35-9 is a valid CAS Registry Number.
