1042687-48-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1042687-48-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,6,8 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1042687-48:
(9*1)+(8*0)+(7*4)+(6*2)+(5*6)+(4*8)+(3*7)+(2*4)+(1*8)=148
148 % 10 = 8
So 1042687-48-8 is a valid CAS Registry Number.
