116315-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116315-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,3,1 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 116315-33:
(8*1)+(7*1)+(6*6)+(5*3)+(4*1)+(3*5)+(2*3)+(1*3)=94
94 % 10 = 4
So 116315-33-4 is a valid CAS Registry Number.
