1295508-35-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1295508-35-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,5,5,0 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1295508-35:
(9*1)+(8*2)+(7*9)+(6*5)+(5*5)+(4*0)+(3*8)+(2*3)+(1*5)=178
178 % 10 = 8
So 1295508-35-8 is a valid CAS Registry Number.
