1235995-98-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1235995-98-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,9,9 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1235995-98:
(9*1)+(8*2)+(7*3)+(6*5)+(5*9)+(4*9)+(3*5)+(2*9)+(1*8)=198
198 % 10 = 8
So 1235995-98-8 is a valid CAS Registry Number.
