130291-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130291-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,9 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130291-41:
(8*1)+(7*3)+(6*0)+(5*2)+(4*9)+(3*1)+(2*4)+(1*1)=87
87 % 10 = 7
So 130291-41-7 is a valid CAS Registry Number.
