Check Digit Verification of cas no

The CAS Registry Mumber 1219733-90-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,7,3 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1219733-90:
(9*1)+(8*2)+(7*1)+(6*9)+(5*7)+(4*3)+(3*3)+(2*9)+(1*0)=160
160 % 10 = 0
So 1219733-90-0 is a valid CAS Registry Number.

New second-order nonlinear optical polyphosphazenes: Convenient postfunctionalization synthetic approach and application of the concept of suitable isolation group

Zeng, Qi,Qiu, Guofu,Ye, Cheng,Qin, Jingui,Li, Zhen

experimental part, p. 229 - 236 (2010/11/04)

The concept of suitable isolation group was applied to the synthesis of nonlinear optical polyphosphazenes that contained different isolation groups attached to the side chains of polyphosphazenes using a post-functional strategy. The loading density of NLO chromophore moieties in the polymers was relatively high (0.60 per unit) and all polymers displayed good processability and relatively good NLO effects, as exemplified by an SHG coefficient (d33) of 67.3 pm V-1 recorded for the polyphosphazene that contained the largest isolation group.
