1191924-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1191924-90-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,9,2 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1191924-90:
(9*1)+(8*1)+(7*9)+(6*1)+(5*9)+(4*2)+(3*4)+(2*9)+(1*0)=169
