117535-90-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117535-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,3 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 117535-90:
(8*1)+(7*1)+(6*7)+(5*5)+(4*3)+(3*5)+(2*9)+(1*0)=127
127 % 10 = 7
So 117535-90-7 is a valid CAS Registry Number.
