83701-39-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83701-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,0 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83701-39:
(7*8)+(6*3)+(5*7)+(4*0)+(3*1)+(2*3)+(1*9)=127
127 % 10 = 7
So 83701-39-7 is a valid CAS Registry Number.
