117734-85-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117734-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,3 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117734-85:
(8*1)+(7*1)+(6*7)+(5*7)+(4*3)+(3*4)+(2*8)+(1*5)=137
137 % 10 = 7
So 117734-85-7 is a valid CAS Registry Number.
