159706-35-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 159706-35-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,7,0 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 159706-35:
(8*1)+(7*5)+(6*9)+(5*7)+(4*0)+(3*6)+(2*3)+(1*5)=161
161 % 10 = 1
So 159706-35-1 is a valid CAS Registry Number.
