235437-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 235437-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,5,4,3 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 235437-83:
(8*2)+(7*3)+(6*5)+(5*4)+(4*3)+(3*7)+(2*8)+(1*3)=139
139 % 10 = 9
So 235437-83-9 is a valid CAS Registry Number.
