1242745-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1242745-87-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,7,4 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1242745-87:
(9*1)+(8*2)+(7*4)+(6*2)+(5*7)+(4*4)+(3*5)+(2*8)+(1*7)=154
154 % 10 = 4
So 1242745-87-4 is a valid CAS Registry Number.
