95826-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 95826-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,8,2 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 95826-34:
(7*9)+(6*5)+(5*8)+(4*2)+(3*6)+(2*3)+(1*4)=169
169 % 10 = 9
So 95826-34-9 is a valid CAS Registry Number.
