291545-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 291545-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,5,4 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 291545-40:
(8*2)+(7*9)+(6*1)+(5*5)+(4*4)+(3*5)+(2*4)+(1*0)=149
149 % 10 = 9
So 291545-40-9 is a valid CAS Registry Number.
