956591-66-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 956591-66-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,6,5,9 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 956591-66:
(8*9)+(7*5)+(6*6)+(5*5)+(4*9)+(3*1)+(2*6)+(1*6)=225
225 % 10 = 5
So 956591-66-5 is a valid CAS Registry Number.
