1033716-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1033716-12-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,7,1 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1033716-12:
(9*1)+(8*0)+(7*3)+(6*3)+(5*7)+(4*1)+(3*6)+(2*1)+(1*2)=109
109 % 10 = 9
