156300-87-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156300-87-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,3,0 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156300-87:
(8*1)+(7*5)+(6*6)+(5*3)+(4*0)+(3*0)+(2*8)+(1*7)=117
117 % 10 = 7
So 156300-87-7 is a valid CAS Registry Number.
