118971-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118971-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,7 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118971-38:
(8*1)+(7*1)+(6*8)+(5*9)+(4*7)+(3*1)+(2*3)+(1*8)=153
153 % 10 = 3
So 118971-38-3 is a valid CAS Registry Number.
