1190935-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1190935-31-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,9,3 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1190935-31:
(9*1)+(8*1)+(7*9)+(6*0)+(5*9)+(4*3)+(3*5)+(2*3)+(1*1)=159
