Check Digit Verification of cas no
The CAS Registry Mumber 137965-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,6 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137965-30:
(8*1)+(7*3)+(6*7)+(5*9)+(4*6)+(3*5)+(2*3)+(1*0)=161
161 % 10 = 1
