1251918-98-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1251918-98-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,1,9,1 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1251918-98:
(9*1)+(8*2)+(7*5)+(6*1)+(5*9)+(4*1)+(3*8)+(2*9)+(1*8)=165
165 % 10 = 5
So 1251918-98-5 is a valid CAS Registry Number.
