1309961-46-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1309961-46-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,9,6 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1309961-46:
(9*1)+(8*3)+(7*0)+(6*9)+(5*9)+(4*6)+(3*1)+(2*4)+(1*6)=173
173 % 10 = 3
So 1309961-46-3 is a valid CAS Registry Number.
