1234896-95-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1234896-95-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,8,9 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1234896-95:
(9*1)+(8*2)+(7*3)+(6*4)+(5*8)+(4*9)+(3*6)+(2*9)+(1*5)=187
187 % 10 = 7
So 1234896-95-7 is a valid CAS Registry Number.
