1138700-42-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1138700-42-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,7,0 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1138700-42:
(9*1)+(8*1)+(7*3)+(6*8)+(5*7)+(4*0)+(3*0)+(2*4)+(1*2)=131
131 % 10 = 1
So 1138700-42-1 is a valid CAS Registry Number.
