1138244-79-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1138244-79-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,2,4 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1138244-79:
(9*1)+(8*1)+(7*3)+(6*8)+(5*2)+(4*4)+(3*4)+(2*7)+(1*9)=147
147 % 10 = 7
So 1138244-79-7 is a valid CAS Registry Number.
