131508-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131508-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,0 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131508-33:
(8*1)+(7*3)+(6*1)+(5*5)+(4*0)+(3*8)+(2*3)+(1*3)=93
93 % 10 = 3
So 131508-33-3 is a valid CAS Registry Number.
