Check Digit Verification of cas no
The CAS Registry Mumber 136994-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,9 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 136994-90:
(8*1)+(7*3)+(6*6)+(5*9)+(4*9)+(3*4)+(2*9)+(1*0)=176
