1123847-35-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1123847-35-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,3,8,4 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1123847-35:
(9*1)+(8*1)+(7*2)+(6*3)+(5*8)+(4*4)+(3*7)+(2*3)+(1*5)=137
137 % 10 = 7
So 1123847-35-7 is a valid CAS Registry Number.
