249622-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 249622-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,9,6,2 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 249622-87:
(8*2)+(7*4)+(6*9)+(5*6)+(4*2)+(3*2)+(2*8)+(1*7)=165
165 % 10 = 5
So 249622-87-5 is a valid CAS Registry Number.
