1542203-87-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1542203-87-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,2,2,0 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1542203-87:
(9*1)+(8*5)+(7*4)+(6*2)+(5*2)+(4*0)+(3*3)+(2*8)+(1*7)=131
131 % 10 = 1
So 1542203-87-1 is a valid CAS Registry Number.
