117845-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117845-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,4 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117845-63:
(8*1)+(7*1)+(6*7)+(5*8)+(4*4)+(3*5)+(2*6)+(1*3)=143
143 % 10 = 3
So 117845-63-3 is a valid CAS Registry Number.
