832135-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 832135-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,2,1,3 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 832135-40:
(8*8)+(7*3)+(6*2)+(5*1)+(4*3)+(3*5)+(2*4)+(1*0)=137
137 % 10 = 7
So 832135-40-7 is a valid CAS Registry Number.
